I don't know CMake at all. Where does the "gtkmm-2.4.lib", which does
not exist, come from?

If I understand this correctly, then auto-linking would basically
require some #pragma lib(gtkmm-vc80-2_4.lib) lines in a header file.
However, how does that header file know what version of the library to
link with?

A way I could think of would be to add a "gtkmm_link.h" file or
something into special subdirectories, one for each version of the
library we provide, such as gtkmm-vc80-2_4. Then, the property sheet
could add the path corresponding to its version to the include search
path.

Finally, we would need to make sure that "gtkmm_link.h" is included
whenever including a gtkmm header file. So we'd basically need to add it
to every gtkmm header. Plus every libxml++ and libglademm header. I'm
not sure we want this.

Is there a better approach to do the auto-linking?
