Re: CMake linking errors [ctwmlib]

Excellent.  Landed in trunk.

It's still ctwm that needs them; ctwmlib is just a mild hack in
building to roll up all the actual objects in one ball, to then link
with a thoroughly trivial main() into the actual binary.  That way we
can just use the lib for building unit tests as well, which makes them
easy [to compile, anyway].

The better solution is probably to use cmake's "Object Libraries"
(which are just an internal rollup of the .o's) instead of making a
real static library.  However, doing that means we'll have to start
requiring cmake 3.1.  Which we probably can and should (we claim 2.6+,
but I wouldn't be surprised if we'd managed to break <2.8 at least,
and maybe <3+ by now), but I figured I'd wait 'till we had some other
big argument to tire everybody out before I brought that up   :)
