Yes. It is obviously that way. But it is kind of non-sense to require a C compiler for a library like Qt4. Either that or it's non-sense to be able to specify that only C++ will be needed, which means to always pull in C in that case: CXX -> search for C _and_ C++ compiler C -> search for C compiler, only Another possibility: Modules that _require_ a C compiler should enable that language themselves.
