Hello team,
I've found myself in a situation where I was unable to build freetype
using meson. The issue seems to be that I was using a variant of libpng
locally built with CMake. As it turns out, with the current build script
meson expects certain files to be named libpngconfig.cmake for example
but libpng installs them as pngconfig.cmake. Meson is hence not able to
recognize them and falls back to the subproject wrap file which doesn't
have that issue. However, this does not work for me because I forbid
downloading additional packages.
To fix this, I changed the meson build file to include a fallback 'png'
library name in addition to the existing 'libpng' (new feature as of
meson v0.60.0). With that, I was successfully able to build freetype.
I'd like to contribute my fix to freetype, please find a patch file
attached. If you have any question regarding my patch and/or the problem
I'm trying to address, please let me know.
Regards
lucebac
