[CMake] Build several targets using cmake --build <dir>

[J Decker]

If the dependencies are already satisfied, and the cmake_make_program can
run mutliple in parallel, then it works great.

I have a cmake script that builds other cmake top level projects; and this
ends up building in parallel on visual studio.

can't do it with any other compiler I use for windows (make can be aliased
on linux to include a /j4).
