[CMake] How to handle find_package inter-dependencies

[Gregor Jasny]

Hello,

I wrote some FindXYZ modules that utilize FindPackageHandleStandardArgs
to find precompiled libraries. Now I have to "find" a library that
itself depends on another library and I wonder what's the recommended
way to do so?

I thought about nesting the find_package calls but then I have the
problem of forwarding options like REQUIRED from the outmost invocation.

Do you have any recommendations?

Thanks,
Gregor
