Subject: [PATCH] Ensure libsolvext dynamic library dependencies are linked

libsolv, when built only build with static link libraries, does not
make a fully usable configuration for static libsolvext to be used
because the CMake and pkgconfig files do not declare the appropriate
libraries to successfully link a static libsolvext that has dynamic library
dependencies.

This patch works around it by doing the declarations here rather than
in libsolv, since it's not easy to fix there, given upstream constraints.
