[FFmpeg-devel] [PATCH] build: rely on pkg-config for libx264 probing.

[Clément Bœsch]

From: Clément Bœsch <clement at stupeflix.com>

This helps populating {c,ld}flags properly without manual user
intervention.

x264 needs to be built with either --bit-depth=8 or --bit-depth=10. Most
distro package the former, so users often have to build their own and
install it in a separated place. Instead of having them to require
--extra-ldflags and --extra-cflags, we can now use pkg-config utils to
append them automatically.

before:
  ./configure --enable-gpl --enable-libx264 --extra-cflags="-I/usr/local/include" --extra-ldflags="-L/usr/local/lib"
after:
  PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./configure --enable-gpl --enable-libx264
