I’ve added a CI build for HarfBuzz, this is a standard ./autogen.sh ./configure make make install sequence. It has dependency upon:
The build works from build 3 onward – set to poll daily.
However, the default build is missing Freetype support, required for pango. The config.log for harfbuzz says “Requested ‘freetype2 >= 12.0.6’ but version of FreeType 2 is 9.22.3”, so we need a newer version of freetype. I’ve added freetype to the CI build.
