Build: Fix rpath in iOS shared libraries

When attempting to configure an iOS/ARM build with Xcode 7.2 and CMake
2.8.12, I got the following errors:

CMake Error at CMakeLists.txt:560 (add_library):
  Attempting to use MACOSX_RPATH without CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG
  being set.  This could be because you are using a Mac OS X version less
  than 10.5 or because CMake's platform configuration is corrupt.
(x 3)

CMake Error at sharedlib/CMakeLists.txt:38 (add_library):
  Attempting to use MACOSX_RPATH without CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG
  being set.  This could be because you are using a Mac OS X version less
  than 10.5 or because CMake's platform configuration is corrupt.
(x 3)

Upgrading to CMake 3.x (tried 3.0 and 3.1) got rid of the errors, but
the resulting shared libs still did not use @rpath as expected.  Note
also that CMake 3.x (at least the two versions I tested) does not
automatically set the MACOSX_RPATH property as claimed.  I could find
nothing in the release notes for later CMake releases to indicate that
either problem has been fixed.  What I did find was this little nugget
of code in the Darwin platform module:

f6b93fbf3a/Modules/Platform/Darwin.cmake (L33-L36)

This sets CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG="-Wl,-rpath," only if you
are running OS X 10.5 or later.  It makes no such check for iOS, perhaps
because shared libraries aren't much of a thing with iOS apps.  In any
event, this commit simply sets CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG if it
isn't set already, and that fixes all of the aforementioned problems.

+1.5.90 (2.0 beta1)
+==================
+
+### Significant changes relative to 1.5.3:
+
+1. Added AVX2 SIMD implementations of the colorspace conversion, chroma
+downsampling and upsampling, integer quantization and sample conversion, and
+slow integer DCT/IDCT algorithms.  When using the slow integer DCT/IDCT
+algorithms on AVX2-equipped CPUs, the compression of RGB images is
+approximately 13-36% (avg. 22%) faster (relative to libjpeg-turbo 1.5.x) with
+64-bit code and 11-21% (avg. 17%) faster with 32-bit code, and the
+decompression of RGB images is approximately 9-35% (avg. 17%) faster with
+64-bit code and 7-17% (avg. 12%) faster with 32-bit code.  (As tested on a
+3 GHz Intel Core i7.  Actual mileage may vary.)
+
+2. Overhauled the build system to use CMake on all platforms, and removed the
+autotools-based build system.  This decision resulted from extensive
+discussions within the libjpeg-turbo community.  libjpeg-turbo traditionally
+used CMake only for Windows builds, but there was an increasing amount of
+demand to extend CMake support to other platforms.  However, because of the
+unique nature of our code base (the need to support different assemblers on
+each platform, the need for Java support, etc.), providing dual build systems
+as other OSS imaging libraries do (including libpng and libtiff) would have
+created a maintenance burden.  The use of CMake greatly simplifies some aspects
+of our build system, owing to CMake's built-in support for various assemblers,
+Java, and unit testing, as well as generally fewer quirks that have to be
+worked around in order to implement our packaging system.  Eliminating
+autotools puts our project slightly at odds with the traditional practices of
+the OSS community, since most "system libraries" tend to be built with
+autotools, but it is believed that the benefits of this move outweigh the
+risks.  In addition to providing a unified build environment, switching to
+CMake allows for the use of various build tools and IDEs that aren't supported
+under autotools, including XCode, Ninja, and Eclipse.  It also eliminates the
+need to install autotools via MacPorts/Homebrew on OS X and allows
+libjpeg-turbo to be configured without the use of a terminal/command prompt.
+Extensive testing was conducted to ensure that all features provided by the
+autotools-based build system are provided by the new build system.
+
+3. The libjpeg API in this version of libjpeg-turbo now includes two additional
+functions, `jpeg_read_icc_profile()` and `jpeg_write_icc_profile()`, that can
+be used to extract ICC profile data from a JPEG file while decompressing or to
+embed ICC profile data in a JPEG file while compressing or transforming.  This
+eliminates the need for downstream projects, such as color management libraries
+and browsers, to include their own glueware for accomplishing this.
+
+4. Improved error handling in the TurboJPEG API library:
+
+     - Introduced a new function (`tjGetErrorStr2()`) in the TurboJPEG C API
+that allows compression/decompression/transform error messages to be retrieved
+in a thread-safe manner.  Retrieving error messages from global functions, such
+as `tjInitCompress()` or `tjBufSize()`, is still thread-unsafe, but since those
+functions will only throw errors if passed an invalid argument or if a memory
+allocation failure occurs, thread safety is not as much of a concern.
+     - Introduced a new function (`tjGetErrorCode()`) in the TurboJPEG C API
+and a new method (`TJException.getErrorCode()`) in the TurboJPEG Java API that
+can be used to determine the severity of the last
+compression/decompression/transform error.  This allows applications to
+choose whether to ignore warnings (non-fatal errors) from the underlying
+libjpeg API or to treat them as fatal.
+     - Introduced a new flag (`TJFLAG_STOPONWARNING` in the TurboJPEG C API and
+`TJ.FLAG_STOPONWARNING` in the TurboJPEG Java API) that causes the library to
+immediately halt a compression/decompression/transform operation if it
+encounters a warning from the underlying libjpeg API (the default behavior is
+to allow the operation to complete unless a fatal error is encountered.)
+
+5. Introduced a new flag in the TurboJPEG C and Java APIs (`TJFLAG_PROGRESSIVE`
+and `TJ.FLAG_PROGRESSIVE`, respectively) that causes the library to use
+progressive entropy coding in JPEG images generated by compression and
+transform operations.  Additionally, a new transform option
+(`TJXOPT_PROGRESSIVE` in the C API and `TJTransform.OPT_PROGRESSIVE` in the
+Java API) has been introduced, allowing progressive entropy coding to be
+enabled for selected transforms in a multi-transform operation.
+
+6. Introduced a new transform option in the TurboJPEG API (`TJXOPT_COPYNONE` in
+the C API and `TJTransform.OPT_COPYNONE` in the Java API) that allows the
+copying of markers (including EXIF and ICC profile data) to be disabled for a
+particular transform.
+
+7. Added two functions to the TurboJPEG C API (`tjLoadImage()` and
+`tjSaveImage()`) that can be used to load/save a BMP or PPM/PGM image to/from a
+memory buffer with a specified pixel format and layout.  These functions
+replace the project-private (and slow) bmp API, which was previously used by
+TJBench, and they also provide a convenient way for first-time users of
+libjpeg-turbo to quickly develop a complete JPEG compression/decompression
+program.
+
+8. The TurboJPEG C API now includes a new convenience array (`tjAlphaOffset[]`)
+that contains the alpha component index for each pixel format (or -1 if the
+pixel format lacks an alpha component.)  The TurboJPEG Java API now includes a
+new method (`TJ.getAlphaOffset()`) that returns the same value.  In addition,
+the `tjRedOffset[]`, `tjGreenOffset[]`, and `tjBlueOffset[]` arrays-- and the
+corresponding `TJ.getRedOffset()`, `TJ.getGreenOffset()`, and
+`TJ.getBlueOffset()` methods-- now return -1 for `TJPF_GRAY`/`TJ.PF_GRAY`
+rather than 0.  This allows programs to easily determine whether a pixel format
+has red, green, blue, and alpha components.
+
+9. Added a new example (tjexample.c) that demonstrates the basic usage of the
+TurboJPEG C API.  This example mirrors the functionality of TJExample.java.
+Both files are now included in the libjpeg-turbo documentation.
+
+10. Fixed two signed integer overflows in the arithmetic decoder, detected by
+the Clang undefined behavior sanitizer, that could be triggered by attempting
+to decompress a specially-crafted malformed JPEG image.  These issues did not
+pose a security threat, but removing the warnings makes it easier to detect
+actual security issues, should they arise in the future.
+
+11. Fixed a bug in the merged 4:2:0 upsampling/dithered RGB565 color conversion
+algorithm that caused incorrect dithering in the output image.  This algorithm
+now produces bitwise-identical results to the unmerged algorithms.
+
+12. The SIMD function symbols for x86[-64]/ELF, MIPS/ELF, macOS/x86[-64] (if
+libjpeg-turbo is built with YASM), and iOS/ARM[64] builds are now private.
+This prevents those symbols from being exposed in applications or shared
+libraries that link statically with libjpeg-turbo.
+
+13. Added Loongson MMI SIMD implementations of the RGB-to-YCbCr and
+YCbCr-to-RGB colorspace conversion, 4:2:0 chroma downsampling, 4:2:0 fancy
+chroma upsampling, integer quantization, and slow integer DCT/IDCT algorithms.
+When using the slow integer DCT/IDCT, this speeds up the compression of RGB
+images by approximately 70-100% and the decompression of RGB images by
+approximately 2-3.5x.
+
+14. Fixed a build error when building with older MinGW releases (regression
+caused by 1.5.1[7].)
+
+15. Added SIMD acceleration for progressive Huffman encoding on SSE2-capable
+x86 and x86-64 platforms.  This speeds up the compression of full-color
+progressive JPEGs by about 85-90% on average (relative to libjpeg-turbo 1.5.x)
+when using modern Intel and AMD CPUs.
+
+
+1.5.3
+=====
+
+### Significant changes relative to 1.5.2:
+
+1. Fixed a NullPointerException in the TurboJPEG Java wrapper that occurred
+when using the YUVImage constructor that creates an instance backed by separate
+image planes and allocates memory for the image planes.
+
+2. Fixed an issue whereby the Java version of TJUnitTest would fail when
+testing BufferedImage encoding/decoding on big endian systems.
+
+3. Fixed a segfault in djpeg that would occur if an output format other than
+PPM/PGM was selected along with the `-crop` option.  The `-crop` option now
+works with the GIF and Targa formats as well (unfortunately, it cannot be made
+to work with the BMP and RLE formats due to the fact that those output engines
+write scanlines in bottom-up order.)  djpeg will now exit gracefully if an
+output format other than PPM/PGM, GIF, or Targa is selected along with the
+`-crop` option.
+
+4. Fixed an issue whereby `jpeg_skip_scanlines()` would segfault if color
+quantization was enabled.
+
+5. TJBench (both C and Java versions) will now display usage information if any
+command-line argument is unrecognized.  This prevents the program from silently
+ignoring typos.
+
+6. Fixed an access violation in tjbench.exe (Windows) that occurred when the
+program was used to decompress an existing JPEG image.
+
+7. Fixed an ArrayIndexOutOfBoundsException in the TJExample Java program that
+occurred when attempting to decompress a JPEG image that had been compressed
+with 4:1:1 chrominance subsampling.
+
+8. Fixed an issue whereby, when using `jpeg_skip_scanlines()` to skip to the
+end of a single-scan (non-progressive) image, subsequent calls to
+`jpeg_consume_input()` would return `JPEG_SUSPENDED` rather than
+`JPEG_REACHED_EOI`.
+
+9. `jpeg_crop_scanlines()` now works correctly when decompressing grayscale
+JPEG images that were compressed with a sampling factor other than 1 (for
+instance, with `cjpeg -grayscale -sample 2x2`).
+

+# GNUInstallDirs
+# --------------

+# Define GNU standard installation directories
+#
+# Provides install directory variables as defined by the
+# `GNU Coding Standards`_.
+#
+# .. _`GNU Coding Standards`: https://www.gnu.org/prep/standards/html_node/Directory-Variables.html
+#
+# Result Variables
+# ^^^^^^^^^^^^^^^^
+#
+# Inclusion of this module defines the following variables:
+#
+# ``CMAKE_INSTALL_<dir>``
+#
+#   Destination for files of a given type.  This value may be passed to
+#   the ``DESTINATION`` options of :command:`install` commands for the
+#   corresponding file type.
+#
+# ``CMAKE_INSTALL_FULL_<dir>``
+#
+#   The absolute path generated from the corresponding ``CMAKE_INSTALL_<dir>``
+#   value.  If the value is not already an absolute path, an absolute path
+#   is constructed typically by prepending the value of the
+#   :variable:`CMAKE_INSTALL_PREFIX` variable.  However, there are some
+#   `special cases`_ as documented below.
+#
+# where ``<dir>`` is one of:
+#
+# ``BINDIR``
+#   user executables (``bin``)
+# ``SBINDIR``
+#   system admin executables (``sbin``)
+# ``LIBEXECDIR``
+#   program executables (``libexec``)
+# ``SYSCONFDIR``
+#   read-only single-machine data (``etc``)
+# ``SHAREDSTATEDIR``
+#   modifiable architecture-independent data (``com``)
+# ``LOCALSTATEDIR``
+#   modifiable single-machine data (``var``)
+# ``LIBDIR``
+#   object code libraries (``lib`` or ``lib64``
+#   or ``lib/<multiarch-tuple>`` on Debian)
+# ``INCLUDEDIR``
+#   C header files (``include``)
+# ``OLDINCLUDEDIR``
+#   C header files for non-gcc (``/usr/include``)
+# ``DATAROOTDIR``
+#   read-only architecture-independent data root (``share``)
+# ``DATADIR``
+#   read-only architecture-independent data (``DATAROOTDIR``)
+# ``INFODIR``
+#   info documentation (``DATAROOTDIR/info``)
+# ``LOCALEDIR``
+#   locale-dependent data (``DATAROOTDIR/locale``)
+# ``MANDIR``
+#   man documentation (``DATAROOTDIR/man``)
+# ``DOCDIR``
+#   documentation root (``DATAROOTDIR/doc/PROJECT_NAME``)
+#
+# If the includer does not define a value the above-shown default will be
+# used and the value will appear in the cache for editing by the user.
+#
+# Special Cases
+# ^^^^^^^^^^^^^
+#
+# The following values of :variable:`CMAKE_INSTALL_PREFIX` are special:
+#
+# ``/``
+#
+#   For ``<dir>`` other than the ``SYSCONFDIR`` and ``LOCALSTATEDIR``,
+#   the value of ``CMAKE_INSTALL_<dir>`` is prefixed with ``usr/`` if
+#   it is not user-specified as an absolute path.  For example, the
+#   ``INCLUDEDIR`` value ``include`` becomes ``usr/include``.
+#   This is required by the `GNU Coding Standards`_, which state:
+#
+#     When building the complete GNU system, the prefix will be empty
+#     and ``/usr`` will be a symbolic link to ``/``.
+#
+# ``/usr``
+#
+#   For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
+#   ``CMAKE_INSTALL_FULL_<dir>`` is computed by prepending just ``/``
+#   to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
+#   as an absolute path.  For example, the ``SYSCONFDIR`` value ``etc``
+#   becomes ``/etc``.  This is required by the `GNU Coding Standards`_.
+#
+# ``/opt/...``
+#
+#   For ``<dir>`` equal to ``SYSCONFDIR`` or ``LOCALSTATEDIR``, the
+#   ``CMAKE_INSTALL_FULL_<dir>`` is computed by *appending* the prefix
+#   to the value of ``CMAKE_INSTALL_<dir>`` if it is not user-specified
+#   as an absolute path.  For example, the ``SYSCONFDIR`` value ``etc``
+#   becomes ``/etc/opt/...``.  This is defined by the
+#   `Filesystem Hierarchy Standard`_.
+#
+# .. _`Filesystem Hierarchy Standard`: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html
+#
+# Macros
+# ^^^^^^
+#
+# .. command:: GNUInstallDirs_get_absolute_install_dir
+#
+#   ::
+#
+#     GNUInstallDirs_get_absolute_install_dir(absvar var)
+#
+#   Set the given variable ``absvar`` to the absolute path contained
+#   within the variable ``var``.  This is to allow the computation of an
+#   absolute path, accounting for all the special cases documented
+#   above.  While this macro is used to compute the various
+#   ``CMAKE_INSTALL_FULL_<dir>`` variables, it is exposed publicly to
+#   allow users who create additional path variables to also compute
+#   absolute paths where necessary, using the same logic.
