[CMake] cmake 2.8.2 win32: invalid escape sequence when finding fortran compiler

[Ryan Pavlik]

Be careful with your use of $ENV{PROGRAMFILES} - it might not give you what
you expect on a 64-bit computer. Since the CMake binary is by default
32-bit, you need some logic to make sure you're looking where you think
you're looking.

patch: contains some cmake script code to figure out what program files env
var is appropriate to search given the *build type* (32-bit or 64-bit)
regardless of the bit mode of the CMake executable itself.
