This was causing issues for my Ubuntu 24.04 build when building
the Distribution preset, so just stash this constant config in
the CMake cache to not worry about it anymore.
The dynamic shared lib build of skia doesn't seem to actually express
any dependencies in its DT_NEEDED section, so we need to force-load
fontconfig into the dependencies of the skia target to avoid runtime
linker errors.
Commit 35392d4d28 moved the
target_*_directories() calls (or rather their include()) before the
target declaration, so they fail because of the undefined target.
We can fix the problem by using global *_directories() instead.
The main incentive is much better performance. We could have gone a bit
further in optimizing the Skia painter to blit glyphs produced by LibGfx
more efficiently from the glyph atlas, but eventually, we also want Skia
to improve correctness.
This change does not completely replace LibGfx in text handling. It's
still used at all stages, including layout, up until display list
replaying.
