Comment(by css@…):

 According to the
 [http://www.cmake.org/cmake/help/cmake2.6docs.html#command:find_path CMake
 FIND_PATH documentation]. CMake will by default include several additional
 search locations. You need to set `NO_DEFAULT_PATH` if you do not want
 CMake to search those additional locations. As noted on that page, you can
 fine-tune the excluded default paths. CMake is working correctly based on
 that page, and you need to fine-tune its search behavior according to your
 need to explicitly avoid the system paths.
