"Error running link command: Argument list too long"

I have a feeling I may be off and on these forums as I try to complete
this. I'm converting a fairly large legacy C project to use CMake
because I'm tired of custom-to-each-machine perl Makefile generation
that we use.

There were other potential ways to resolve the dependencies other than
such a massive static library, but I don't know of a good CMake-style
way to integrate the --start-group and --end-group flags without
resorting to a bunch of really terse coding in my CMakeLists.txt.
Since part of my goal here is to show how much simpler it is to get
things going with CMake, I'd just rather not. If you know of a
property/variable that'll automatically toss in --start-group and
--end-groups I would love to know.

It definitely fixed the problem. Thanks a bunch.
