That makes sense, running it from the build root. Is that just because
'make check' is slow, or? (sanity-test is really slow.)

Hm, not really. You just add an 'env' argument when declaring the test, e.g.:
    egl_sym_check = find_program('wayland-egl-symbols-check')
    test_egl_syms = test('egl-symbols', egl_sym_check, env: [
'WAYLAND_EGL_LIB=@0@'.format(lib_wayland_egl) ])

Yeah, that doesn't work.

It's fair enough. I'm just trying to find out the balance of these:
for instance, if it's no problem to add environment variables with
Meson, do you still want to push it for reason #1, or?
