Purpose: Added require alternative for libmfx in the case that pkg-config cannot find libmfx. On Linux, most people likely get libmfx via https://github.com/lu-zero/mfx_dispatch , but on Windows, the most well-known way to get libmfx is via the Intel Media SDK, which provides a static build of libmfx.lib and also provides the source code for building libmfx yourself. If built this way, there are no pkg-config files to be found. Comments: -- configure: Altered enabled libmfx step to use use_pkg_config() instead of require_pkg_config(), and, if use_pkg_config() fails, it falls back to require(). Also added explanatory comment. Note that the reason that require() is passed -llibmfx as the last argument, instead of -lmfx, is the file name for the library produced from the Intel Media SDK starts with "libmfx". Apparently, the filename for the library produced via https://github.com/lu-zero/mfx_dispatch starts with "mfx".
