The branch looks like a great start!  However, I do not think looking for

 -DLINK_LIBRARIES:STRING=

as a literal will be reliable.  There is no reason projects have to include
the :STRING part.  I'd rather this be made a first-class keyword argument
to try_compile or something like that.  It could also be useful for the
full-project form of the command in addition to the single-source form.
