Great!

Let's not optimize prematurely.  It is much simpler to have a single
approach that works everywhere.  The direct-compile approach requires
extra/duplicate infrastructure like _CMAKE_${lang}_CREATE_OBJECT_FILE
to be maintained and it may not exactly match how the project will be
generated (where the try_compile approach does).
