It's slightly more awkward than autotools, but it works fine. You
create a toolchain file describing the set of tools you want to build
with, and cmake will use them rather than the system ones:

https://cmake.org/cmake/help/v3.0/manual/cmake-toolchains.7.html

I use this one (for example) to cross-compile from ubuntu:xenial to
64-bit Windows:

https://github.com/jcupitt/build-win64/blob/master/8.5/Toolchain-x86_64-w64-mingw32.cmake

(I'm not a cmake expert, I'm sure that can be improved on, but it does
seem to work)
