Native Cmake for MSYS?

Has anyone had any success building Cmake for Msys or are there binaries 
available anywhere?

I am building Doom 3 with MinGW but the path handling isn't working 
properly: I have to set manually /mingw/lib and /mingw/include to PATH 
variable so that Cmake can find correct libraries and headers. This 
might be fixable by modifying CMakeLists.txt but I know nothing about 
Cmake at the moment.
