FYI, CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES is not documented by
CMake as a publicly available value. It is an internal implementation
detail, though I doubt it is going away.

CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES contains hard-coded
guesses on specific platforms for typical system directories.
It pre-dates CMake's modern functionality that detects the real
implicit library search path used by the compiler front-end.
Those results are stored in
CMAKE_${lang}_IMPLICIT_LINK_DIRECTORIES
where "${lang}" is "C", "CXX", "Fortran", etc. for each language
that has been enabled. This one is publicly documented:
http://www.cmake.org/cmake/help/v2.8.8/cmake.html#variable:CMAKE_LANG_IMPLICIT_LINK_DIRECTORIES
Use that instead. It first appeared in CMake 2.8.0.
