​​The process to build GMP is described in the manual:
<http://gmplib.org/manual/Installing-GMP.html#Installing-GMP>

You have to first build the library, install it in your development
environment, then build your program.​​ If you just scram every files in
eclipse CDT, it will blindly try to build everything including optimized
assembly for all supported architectures, which won't work. It will
probably miss a few define directives needed to build correctly.

For more information on using a gcc-like environment on windows, you should
read about mingw and msys or cygwin.
