GMP doesn't exist for Windows, so what you need (and should already be 
installed as a dependency of GNU Radio, or rather the `gnuradio-core` package) 
is `mpir`.

I'm striving to make things as painless as possible on Windows, but there are 
inevitable frictions that happen because of its differences from Linux and the 
fact that the conda packages are relatively new and building OOTs is still the 
frontier.

What OOT in particular are you trying to build? Maybe there are other things 
that are needed to get it working if nobody has done it before successfully on 
Windows. The full output from CMake would also be helpful to really see what's 
going wrong.
