Yes it did, but i think I might have found the problem. I should not export
the cmake files themselves but only the directory containing them. And there
where i want to use the macro defined in the cmake file use rosbuild_include to
manually include it.
Apparently I had a old version (with a different name) of the package that
still contained the export tag but not the file.
