# Note on x264 versioning:
# The pc file exports "0.164.<N>" where is the number of commits.
# The binary releases on https://artifacts.videolan.org/x264/ are named x264-r<N>-<COMMIT>.
# With a git clone, this can be determined by running `versions.sh`.
# With vcpkg_from_gitlab, we modify `versions.sh` accordingly.
# For --editable mode, use configured patch instead of vcpkg_replace_string.
