I'm attempting to use homebrew to build and install ffmpeg (homebrew currently uses 5.1.2) with SVG support on macOS (12.5.1, M1 Pro) . This requires the use of librsvg (homebrew currently uses 2.55.1).
During the (re-)installation, the process fails with:
ERROR: librsvg-2.0 not found using pkg-config
The following was done:
brew edit ffmpegto includedepends_on "librsvg"below the existing dependencies, and--enable_librsvgwithin the installation args.brew reinstall ffmpeg --build-from-source(ffmpegwas installed prior).
librsvg is detected as a dependency and installed prior to the re-installation of ffmpeg, as seen in its installation log.
Running pkg-config --exists librsvg-2.0 returns exit code 0. This is what ffmpeg uses to check for dependencies at point of build.
Result of brew config: ([...] changes are mine)

There are no envvar overrides such as PKG_CONFIG_PATH as far as I can see in my session.
I imagine these are being set / changed during brew's installation process, but librsvg's folder is included in the path list within the env vars shown when the installation is ran with -vvv.
Oddly, I had ran through the same process about a month ago and it had worked. I'm not sure what's changed since!
The librsvg package can be found alongside all other brew packages in /opt/homebrew/Cellar[/librsvg], and /opt/homebrew/opt[/librsvg]
