[cmake-developers] Listing all targets (was: Wrapping functions in CMake)

[David Cole]

Attached is a patch file of my first attempt. I can iterate some more
on this (better testing, add docs, clarify existing docs, address
anybody's comments, submit to stage) next week. Attached now in case
anybody wants to try it out over the weekend.


Cheers,
David C.
