Strange.

I can not see why it would prefer c:\Cygwin\bin over c:\Python26...

Can you build CMake from source on this machine?

If so, can you add some print statements here:
Source/kwsys/SystemTools.cxx

kwsys_stl::string SystemTools::FindProgram(
...

Just add std::cout << tryPath.c_str() just before each call to 
SystemTools::FileExists in that function.
