This patch from Philip Lowman creates a REALPATH mode in the
get_filename_component command. It is like ABSOLUTE, but will also
resolve symlinks (which ABSOLUTE once did but was broken long ago).
See issue #8423.
The patch used to fix this bug used SystemTools::GetRealPath which works
only for existing files. It broke the case of using the command
get_filename_component for a non-existing file. Also, it changed
long-standing behavior in a possibly incompatible way even for existing
files. This reverts the original fix and instead updates the
documentation to be consistent with the behavior.
- Fixed CollapseFullPath to work on relative paths with base paths
not in the current working directory.
- INCLUDE command now supports relative paths (using above fix).
- Added ABSOLUTE option to GET_FILENAME_COMPONENT command to
unwind symlinks and relative paths.
- Fixed libName_EXPORTS macro definition to be valid C identifier.
- Added DEFINE_SYMBOL target propterty for customizing the export symbol.
- Implemented LINK_FLAGS target propterty for libraries in VC6 and VC7.
Several of these fixes were contributed by Gareth Jones.
