use enable_language as needed in cmake outputs? about prefab HOT 3 OPEN

Probably fine to just use enable_language? I'd at least be content to start with that and change the behavior later if that causes issues.

For Android, this won't pose any problems because a c++ compiler is guaranteed to exist.

This change will touch #134.
OpenSSL is pure C and does not need a C++ linker.

It's not a missing compiler that I'm worried about, I'm curious if there are CMakeLists.txt files out there that behave differently based on whether the project enables C++ or not. If some vendored dependency pulled in via add_subdirectory builds additional libraries that aren't needed for C users, for example. It's a stretch, so probably fine to ignore until we hear about it causing a problem in the real world.
