Create Mac package/disk image. This requires pkgbuild and productbuild, which
are installed by default on OS X 10.7 and later and which can be obtained by
installing Xcode 3.2.6 (with the "Unix Development" option) on OS X 10.6.
Packages built in this manner can be installed on OS X 10.5 and later, but they
must be built on OS X 10.6 or later.
are installed by default on OS X 10.7 and later.
In order to create a Mac package/disk image that contains universal
x86-64/i386/ARM binaries, set any of the following CMake variables:
x86-64/ARM binaries, set the following CMake variable:
* `OSX_32BIT_BUILD`: Directory containing an i386 (32-bit) Mac or iOS build of
libjpeg-turbo to include in the universal binaries
* `IOS_ARMV8_BUILD`: Directory containing an ARMv8 (64-bit) iOS build of
libjpeg-turbo to include in the universal binaries
You should first use CMake to configure i386 and/or ARMv8 sub-builds of
libjpeg-turbo (see "Build Recipes" and "Building libjpeg-turbo for iOS" above)
in build directories that match those specified in the aforementioned CMake
variables. Next, configure the primary build of libjpeg-turbo as an
out-of-tree build, specifying one or more of the aforementioned CMake
variables, and build it. Once the primary build has been built, run
`make dmg` from the build directory. The packaging system will build the
sub-builds, use lipo to combine them into a single set of universal binaries,
then package the universal binaries.
