windres has a handy feature of allowing us to feed it an executable and
it will give an error code depending on whether that executable has a
resource section or not. We can use that feature to create a quick test
to verify the distributable has the resource information on it.
These tests use a variety of sample code (with some of the larger files
removed, so they are not complete!) and verifies that they all compile
successfully.
These tests check that we can compile programs that use a variety of
different sets of dependencies. Each program will only be compiled with
the set of dependencies it relies on.
