Implement an initial Wayland client, which will build if

the wayland-client development libraries are detected
(or if -DWITH_WAYLAND:BOOL=ON is set). It is currently
view-only, but inputs will be implemented soon.

It uses the software SHM interface, which means it does not
require GL acceleration to run. It should be compatible
with any compositor

set_complex_link_libraries shouldn't be required anymore on master. This was dropped some while ago. The cmake function was only kept for compatibility with older clients. You should only need to add freerdp to ${MODULE_PREFIX}_LIBS}
