It did find a libgmp, it just couldn't use it because it was for a different target/ABI. "gcc" is the wrong compiler for a mingw mpfr build. That should be i686-w64-mingw32-gcc instead. I see that gmp forces use of -m32 for the build. That is harmless for the mingw32 compiler which only emits 32-bit code. But if gmp was also built with "gcc", then you would have a 32-bit x86-linux libgmp and a 64-bit x86_64-linux libmfpr which can't be linked together. So I would suspect that they were both built with the wrong compiler. Not obvious what is wrong, but if you tried a build with CC=gcc in your environment, then it might fail this way.
