RPATH support is activated on targets that have the MACOSX_RPATH
property turned on.
For install time, it is also useful to set INSTALL_RPATH to help
find dependent libraries with an @rpath in their install name.
Also adding detection of rpath conflicts when using frameworks.
Make handling of directory separators consistent between
non-bundle and bundle code.
Remove xcode specific flag from cmTarget when getting install_name.
Add (more) consistent convenience functions in cmTarget to get
directories inside of bundles and frameworks to add files to.
This refactor also fixes bug #12263 where frameworks
had the wrong install name when SKIP_BUILD_RPATH.
Also make install_name for frameworks consistent between Makefile
and Xcode generator.
In commit 236133e7 (Handle targets in the LINK_LIBRARIES of try_compile,
2013-02-09) an error return case was added without closing the file in
progress. Add the missing fclose() call.

In commit 0c727b90 (install(EXPORT): Force absolute paths for usr-move,
2013-03-08) and commit d4774140 (configure_package_config_file: force
absolute paths for usr-move, 2013-01-24) we supported Linux
distributions implementing the "/usr move" by assuming that installation
to (/usr)?/lib(64)? represents a non-relocatable system package.
When cross-compiling one may prepare a package for installation into a
system location on a target machine but install the package files on the
*host* machine inside another path for use with CMAKE_FIND_ROOT_PATH.
In this case the package development files must still be relocatable.
Handle "/usr move" with a new approach that works with relocatable
files. Teach configure_package_config_file and install(EXPORT) to
generate special logic in a package configuration file or targets file
for installation under (/usr)?/lib(64)?. Teach the file to recognize
when it is loaded through a symlink that refers to the same realpath as
its original install destination. In such a case, use the original
install prefix. Otherwise, compute the prefix relative to the current
file location to make it relocatable.
In VS IDE generators add a pre-build event to perform automoc instead of
using a separate custom target. This reduces the number of targets in the
.sln that need to be loaded by the IDE.
This also works around a VS 11 bug as discussed in issue 13900.

When called with a non-existent LHS target name the user may be trying
to add file-level dependencies. Clarify the error message to explain
the difference between target-level and file-level dependencies. Point
the reader at the commands and options needed for the latter.
