- Simplify error checking when using execute_process.
- Set BUILD_SHARED_LIBS to OFF when building dependencies.
This is normally not needed, but msgpack interprets an unset
BUILD_SHARED_LIBS to build a shared library, which is the opposite of
the cmake behavior.
- Move function check_lua_module to Util.cmake.
- Remove unnecessary code.
- Make variable naming more consistent
- Remove unused code
- Use consistent casing. Variable names such as LibLuV_LIBRARIES is
needlessly jarring, even if the name might be technically correct.
- Use title casing for packages. find_package(unibilium) requires the
find_module to be named "Findunibilium.cmake", which makes it harder
to spot when scanning the files. Instead, use "Unibilium".
