find_program() still requires some valid PATH to search. If I manually
add PATH=c:\mingw\bin to Eclipse environment variables, the windres.exe
could be found without any problems. The best way where to let CMake
specify RC compiler path during generator creation using cmake-gui. What
about applying this patch: http://public.kitware.com/Bug/view.php?id=4068
