Well, pragma(lib) only works if you are compiling the project, not importing it
(i.e: Every pragma(lib) in core.sys.windows doesn't work with certain build
configurations).  pragma(framework) will suffer from the same limitation.

The build tools are better placed to manage this, assumedly because you already
explicitly say what your dependencies are, and it can merge all library
dependencies together in the final link command.
