Unfortunately wlc 0.0.10 seems to be the cause for segfaults on sway,
way-cooler and orbment.
This will also build wlc with all optional packages (i.e. zlib,
valgrind and doxygen).
While the last wlc upgrade (05d79c03ec)
makes it possible to build sway 0.14.0 it also breaks the current build
of sway 0.13.0.
Unfortunately sway 0.14.0 segfaults on launch and I couldn't fix it yet
(there are multiple upstream issues as well). I'll overwrite the wlc
version for sway in order to have a usable version in nixpkgs for the
meantime.
Building the manual requires docbook_xsl; in sandboxed environments,
the build would fail due to being unable to download missing docbook
resources.
Also include some minor improvements to the build recipe:
- use fetchFromGitHub
- move build-time dependencies to nativeBuildInputs
