I had that covered. I just shortened the example not to confuse the OP.

	IF(CMAKE_SIZEOF_VOID_P MATCHES 4)
	string (REPLACE "\\" "/" PGM_FILES $ENV{PROGRAMFILES})
	ELSE(CMAKE_SIZEOF_VOID_P MATCHES 4)
	# On WIN64 use the 64 bit program files..
	string (REPLACE "\\" "/" PGM_FILES $ENV{ProgramW6432})
	ENDIF(CMAKE_SIZEOF_VOID_P MATCHES 4)
