I am pretty certain the file has to be called CMakeLists.txt in order 
for cmake to recognize it.  If I rename it to CMakeLists.win32.txt then 
cmake complains:

CMake Error: The source directory 
"/Developer/x86_64/build/git-src-fontconfig" does not appear to contain 
CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.


I could make it print an erro message if it detects a non-WIN32 
platform, like this:

if (NOT WIN32 OR (MINGW OR MSYS OR CYGWIN))
   message(FATAL_ERROR "This CMake project is intended only for native 
WIN32 compilation.  For any other platforms please use the autotools 
./configure script.")
endif (NOT WIN32 OR (MINGW OR MSYS OR CYGWIN))
