Lucian Petrut d024506f64 cmake: allow building CLI tools on Windows
For now, we'll only build some of the Ceph CLI binaries when
targeting Windows. In order to avoid over complicating the
cmake files, it was decided that the build script should pick
the targets that are to be compiled.

To keep the build script relatively simple, we'll stop supporting
Ninja, sticking to "make". Another reason for that is that some
targets cannot be compiled using Ninja:
