Previously we checked for this flag by parsing the version number of GCC
out of 'gcc --version', but this is not reliable because the format can
vary greatly. Now we run 'gcc -v --help' and look for '-isysroot' in
the list of options.
We also now store the result on a per-language basis in the per-compiler
info file "CMake<LANG>Compiler.cmake". This is necessary to make it
accessible from try-compile projects so that they generate correctly.
We used to suppress generation of -I/usr/include (and on OSX also
-I/usr/local/include). This behavior seems to cause more trouble than
it's worth, so I'm removing it until someone encounters the original
problem it fixed. See issue #8598.
Some OS X linkers want a 'dylib_' prefix on the -compatiblity_version
and -current_version flags while others do not. This passes the flags
through gcc instead since it never wants the prefix and translates the
flags for the linker correctly.
- ld flags -dylib_compatibility_version and -dylib_current_version
are libtool flags -compatibility_version and -current_version
- OSX 10.3 does not like the dylib_ prefixes.
- Fixes repeated rebuild of bundles by Makefile generators
- Add special rules to copy sources to their
MACOSX_PACKAGE_LOCATION bundle directory
- Remove MacOSX_Content language hack
- Remove EXTRA_CONTENT property
- Remove MACOSX_CONTENT
- Remove corresponding special cases in object names
- Move runtime path ordering out of cmComputeLinkInformation
into its own class cmOrderRuntimeDirectories.
- Create an instance of cmOrderRuntimeDirectories for runtime
path ordering and another instance for dependent library
path ordering.
- Replace CMAKE_DEPENDENT_SHARED_LIBRARY_MODE with explicit
CMAKE_LINK_DEPENDENT_LIBRARY_FILES boolean.
- Create CMAKE_LINK_DEPENDENT_LIBRARY_DIRS boolean.
- Create variables to specify -rpath-link flags:
CMAKE_SHARED_LIBRARY_RPATH_LINK_<LANG>_FLAG
CMAKE_EXECUTABLE_RPATH_LINK_<LANG>_FLAG
- Enable -rpath-link flag on Linux and QNX.
- Documentation and error message updates
- Split IMPORTED_LINK_LIBRARIES into two parts:
IMPORTED_LINK_INTERFACE_LIBRARIES
IMPORTED_LINK_DEPENDENT_LIBRARIES
- Add CMAKE_DEPENDENT_SHARED_LIBRARY_MODE to select behavior
- Set mode to LINK for Darwin (fixes universal binary problem)
- Update ExportImport test to account for changes
cmMakefile.cxx, but now in the platform files and are now valid for the
target platform, not the host platform.
New variables CMAKE_HOST_WIN32, CMAKE_HOST_UNIX, CMAKE_HOST_APPLE and
CMAKE_HOST_CYGWIN have been added in cmMakefile.cxx (...and have now to be
used in all cmake files which are executed before
CMakeSystemSpecificInformation.cmake is loaded). For compatibility the old
set is set to the new one in CMakeDetermineSystem.cmake and reset before the
system platform files are loaded, so custom language or compiler modules
which use these should still work.

Tested with various gcc, XCode, MSVC7, sdcc
For OSX when doing TRY_COMPILE() CMAKE_OSX_ARCHITECTURES is used, if there are different results an error is generated. CMAKE_OSX_ARCHITECTURES can be overwritten for the TRY_COMPILES with CMAKE_TRY_COMPILE_OSX_ARCHITECTURES.
