Currently ‘cmake-build-system’ does not support cross-compilation, which
is becoming more and more of a problem.  For instance, it prevents
cross-compilation of Guix:

--8<---------------cut here---------------start------------->8---
$ guix build guix --target=aarch64-linux-gnu -n
guix build: error: gnu/packages/ssh.scm:59:2: libssh-0.7.4: build system `cmake' does not support cross builds
--8<---------------cut here---------------end--------------->8---

I think CMake supports cross-compilation in theory, so we should try to
implement it.
