CMake subprojects

Meson can now directly consume CMake based subprojects with the CMake module.

Using CMake subprojects is similar to using the "normal" meson subprojects. They also have to be located in the subprojects directory.

Example:

add_library(cm_lib SHARED ${SOURCES})

cmake = import('cmake')

# Configure the CMake project
sub_proj = cmake.subproject('libsimple_cmake')

# Fetch the dependency object
cm_lib = sub_proj.dependency('cm_lib')

executable(exe1, ['sources'], dependencies: [cm_lib])

It should be noted that not all projects are guaranteed to work. The safest approach would still be to create a meson.build for the subprojects in question.
