have you tried the autotools build system? (i havent pushed it to
savannah yet, as it's still experimental, find it on tool [1])

it looks like a list of files rather than a build system. is that
intended? there is no configure script. how is this supposed to be used?

library names typically start with "lib", so there should be no trouble.

the build system should at least implement what the upstream build
system does. please explain how to configure yours, how CMakeLists will
call modelgen....
i consider (at least) a 'dist' target and objdir!=srcdir mandatory.
would that be possible?
