What piece of code should handle those imported targets? I thought it is
cmMakefile::AddLinkLibraryForTarget, but it doesn't do that. Should a
local generator check itself whether a library is an imported target?
I thought this work is done transparently for generators.
I use cmLocalVisualStudio6Generator as a reference and looked at the
cmLocalUnixMakefileGenerator3 but still do not understand how to distinguish
imported link libraries from other ones in a LocalGenerator.
Please, give me a point.
Now I'm working in the CVS source.
Thanks,
Sergey
