Although there is little chance that we will ever have a package
conflict on OS X, the convention from our Linux packages is to use the
package name, not the project name, for the name of the documentation
directory.
- GNUInstallDirs: any directory variable can now reference any other
directory variable by including its name in angle brackets (<>).
- Changed the documentation of the directory variables in BUILDING.md
accordingly. This commit also includes some formatting tweaks to
that section (using boldface for directory names, as is our
convention.)
- Changed the package scripts such that they use
CMAKE_INSTALL_DATAROOTDIR rather than CMAKE_INSTALL_DATADIR.
- We no longer override the install dir. defaults on Windows unless
performing an official build. It may be useful, for instance, to
use the GNU defaults when installing into an MSYS environment.
This builds upon the existing GNUInstallDirs module in CMake but adds
the following features to that module:
- The ability to override the defaults for each install directory
through a new set of variables (`CMAKE_INSTALL_DEFAULT_*DIR`).
Before operating system vendors began shipping libjpeg-turbo, it was
meant to be a run-time drop-in replacement for the system's
distribution of libjpeg, so it has traditionally installed itself
under /opt/libjpeg-turbo on Un*x systems by default. On Windows, it
has traditionally installed itself under %SystemDrive%\libjpeg-turbo*,
which is not uncommon behavior for open source libraries (open source
SDKs tend to install outside of the Program Files directory so as to
avoid spaces in the directory name.) At least in the case of Un*x,
the install directory behavior is based somewhat on the Solaris
standard, which requires all non-O/S packages to install their files
under /opt/{package_name}. I adopted that standard for VirtualGL and
TurboVNC while working at Sun, because it allowed those packages to be
located under the same directory on all platforms. I adopted it for
libjpeg-turbo because it ensured that our files would never conflict
with the system's version of libjpeg. Even though many Un*x
distributions ship libjpeg-turbo these days, not all of them ship the
TurboJPEG API library or the Java classes or even the latest version
of the libjpeg API library, so there are still many cases in which it
is desirable to install a separate version of libjpeg-turbo than the
one installed by the system. Furthermore, installing the files under
/opt mimics the directory structure of our official binary packages,
and it makes it very easy to uninstall libjpeg-turbo.
For these reasons, our build system needs to be able to use
non-GNU-compliant defaults for each install directory if
`CMAKE_INSTALL_PREFIX` is set to the default value.
- For each directory variable, the module now detects changes to
`CMAKE_INSTALL_PREFIX` and changes the directory variable accordingly,
if the variable has not been changed by the user.
This makes it easy to switch between our "official" directory
structure and the GNU-compliant directory structure "on the fly"
simply by changing `CMAKE_INSTALL_PREFIX`. Also, this new mechanism
eliminated the need for the crufty mechanism that previously did the
same thing just for the library directory variable.
How it should work:
- If a dir variable is unset, then the module will set an internal
property indicating that the dir variable was initialized to its
default value.
- If the dir variable ever diverges from its default value, then the
internal property is cleared, and it cannot be set again without
unsetting the dir variable.
- If the install prefix changes, and if the internal property
indicates that the dir variable is still set to its default value,
and if the dir variable's value is not being manually changed at the
same time that the install prefix is being changed, then the dir
variable's value is automatically changed to the new default value
for that variable (as determined by the new install prefix.)
- The directory variables are now always cached, regardless of whether
they were set on the command line or not. This ensures that they can
easily be examined and modified after being set, regardless of how they
were set.
This was made possible by the introduction of the aforementioned
`CMAKE_INSTALL_DEFAULT_*DIR` variables.
- Improved directory variable documentation (based on descriptions at
https://www.gnu.org/prep/standards/html_node/Directory-Variables.html)
- The module now allows "<DATAROOTDIR>" to be used as a placeholder in
relative directory variables.
It is replaced "on the fly" with the actual path of
`CMAKE_INSTALL_DATAROOTDIR`.
This should more closely mimic the behavior of the old autotools build
system while retaining our customizations to it, and it should retain
the behavior of the old CMake build system.

This might be slightly more controversial, since it changes the CMake and
autotools project names and the binaty package names to "mozjpeg", and it
changes the default install directory to /opt/mozjpeg. To me, this makes much
more sense, but it does represent a change in operational behavior, which is
why I put it in a separate commit.
This patch does the following:
-- Implements some (hopefully non-controversial) changes to the package
descriptions, in order to prevent confusion (the existing descriptions from
libjpeg-turbo are not appropriate for mozjpeg.)
-- Replaces "libmozjpeg" with "mozjpeg" in all documentation and comments. The project is called "mozjpeg", and it doesn't actually generate a library called
"libmozjpeg", so it doesn't make sense to use "libmozjpeg" to describe it.
-- Replaces "MozJPEG" with "TurboJPEG" in all documentation and comments.
"MozJPEG" appears to have been the product of blindly searching/replacing
instances of "Turbo". TurboJPEG is the name of the API, and that name still
applies to the implementation in mozjpeg. Furthermore, the TurboJPEG libraries
are still called "libturbojpeg" in mozjpeg.
-- Attempts to remove build instructions that are irrelevant or not applicable
to mozjpeg. Further work possibly needs to be done here-- for instance, it
doesn't make much sense to have build instructions for mobile devices when the
library is not intended to be used for decoding.
-- Changes the vendor in the DEB and RPM files from "The libmozjpeg Project" to
"Mozilla Research".
-- Changes the source tarball location in the RPM spec file to correctly point
to the release tarball on github.
-- Changes the source directory in the RPM spec file to "mozjpeg-%{version}",
which is the actual name of the source directory in the mozjpeg tarballs.
-- The Mac and Cygwin packages will now be created with the directory structure defined by the configure variables "prefix", "bindir", "libdir", etc., with the exception that the docs are always installed under /usr/share/doc/{package_name}-{version} on Cygwin and /Library/Documentation/{package_name} on Mac.
-- Fixed a duplicate filename warning when generating RPMs with the default prefix of /opt/libjpeg-turbo.
-- Moved the TurboJPEG libraries out of the system directory on Windows and Mac. It is no longer necessary to put them there, since we are not trying to be backward compatible with TurboJPEG/IPP anymore.
-- Fixed an issue whereby building the "installer" target on Windows would not build the Java JAR file, thus causing an error if the JAR had not been previously built.
-- Building the "install" target on Windows will now install libjpeg-turbo into c:\libjpeg-turbo[-gcc][64] (the same directories used by the installers.) This can be overridden by setting CMAKE_INSTALL_PREFIX.
-- The Java classes on all platforms will now look for the JNI library in the directory under which the build/packaging system installs it.
