Cygwin's installation directory is mainly needed to use some programs of it, irrespectively of the target architecture. However, find_path does not consider cygwin with architecture different than the target architecture. This is because cygwin's installation path is retrieved from the registry. WOW64 view is not used by find_path if generating for 32-bit architecture and vice versa, so cygwin is not found then. find_program tries both views, this way a 64-bit cygwin may be used for 32 bit build and vice versa.
