Message : meson: link tests and benches against shared library, not static library This makes the tests, and especially benches, more realistic, since xkbcommon is almost always used as a shared library. Also significantly reduces the build time with LTO enabled (for me, from 90s to 30s). Signed-off-by: Ran Benita <ran@unusedvar.com>

If this fails, please update the appropriate .map file (adding new version
