 After you compile the library, go to its include directory, create a folder "mpeg2dec" in there and copy all files from the include folder in this subfolder. You will end up with 2 directories, "include" and "include\mpeg2dec" with the same files. This is needed, as ScummVM includes files from the "mpeg2dec" directory
