If you just want to use the GC, you don't have to build it with cmake, having 
a "Finder" for cmake is good enough.

...but if you need to integrate the GC build into your projects build, 
converting it to cmake might make sense.
If you don't convert it, you have to use something like add_custom_target() to 
build GC, and then you have to care to call the right make with the right 
makefiles depending on the platform.

If you convert GC to cmake, cmake takes care of a lot of things, but you still 
may have to care e.g. for different compile flags necessary for different 
platforms or different compiler versions.

Yes.

That would be a good thing.
