yuzu requires CMake 3.15 yet find_program was using REQUIRED, which is only available on 3.18 and later. Instead, we check for "<VAR>-NOTFOUND". In addition, check for additional requirements before building libusb or FFmpeg with autotools. Otherwise, CMake configuration will pass yet compilation will fail.
