[CMake] Problem with CMake _not_ failing due to unsatisfied indirect project dependencies

Sat Jul 2 14:57:01 EDT 2011

Hello,
I received report from a Debian testing user (using cmake 2.8.4 from
Ubuntu repo) that gadu_protocol plugin for Kadu IM[1] was linked
improperly (it didn't link to libgadu) and refused to load. After
small investigation we found out that it was due to missing gnutls.pc
in his system. I'm attaching some logs. Note that Kadu IM checks for
libgadu using the following command:
    pkg_search_module (LIBGADU REQUIRED libgadu>=${LIBGADU_MIN_VERSION})

My question here is whether there is a way to force CMake to fail in
such case, informing user about unsatisfied dependencies. Or maybe
it's just a regular bug that I should report to your bug tracking
system?

Cheers,
Bartosz
