This carries include directories and the required link flags. Several libraries brought in through pkg_check_modules aren't linked correctly using the _LDFLAGS variables. Instead, they link the libraries directly with `-l`. This is problematic because it doesn't properly pull in the actual directory of the library being linked when it is not in a system library directory. Likewise, the necessary include directories for several of these targets aren't properly set either. Linking against the imported targets automatically pulls in the necessary include directories.
