Can be simplified a bit:
_xlib_lease = get_option('xlib-lease')
if _xlib_lease == 'auto'
with_xlib_lease = with_platform_x11 and with_platform_display
else
with_xlib_lease = _xlib_lease == 'true'
endif
(We also usually try to avoid changing the type of a var, and meson might
start being more strict with types in future releases)
