meson will set add -DHYPRLAND_DEBUG to CXXFLAGS during compilation of
debug builds. this avoids NDEBUG issues with wlroots and ensures asserts
will also work on release builds.
prevents build-failure when xwayland is disabled to to
add_project_arguments('-DNO_XWAYLAND', language: 'cpp')
beeing called after the required wayland protocols have been built.
this makes for a far better experience in combination with wlroots,
since that whole makefile mess is not required.
Additionaly, handling of wayland protocol sources is also slightly
better, but could be improved with mesons inbuilt wayland module.
To build Hyprland using meson:
meson _build -Ddefault_library=static
ninja -C _build
ninja -C _build install
