This provokes a new warning from meson on a linux-static build:

If we're building statically and we can't find a static
library then (a) we shouldn't print a WARNING and
(b) we shouldn't then conclude that we've found gdm.
Hmmm, no clue what's wrong here, since I basically did declare it like
all other libraries are declared, too (so this problem should have
shown up somewhere else already?)... Paolo, do you have any ideas
what's going on here?
In attempting to replicate I found all the dynamic libs blow up:
WARNING: Static library 'xkbcommon' not found for dependency 'xkbcommon',
may not be statically l
Run-time dependency xkbcommon found: YES 1.0.3
I do vaguely recall complaining about new meson warnings for
static library detection in the past as well:

So is this a general problem with static libs. BTW I didn't catch this
because I only build user with --static as I thought system --static was
flakey anyway.
I'm not doing a system build in this case... Looking at some of
those older threads, it looks like part of the answer is that
for dependencies that we don't need for linux-user mode we should
guard the test with some suitable if condition so we don't create
the dependency unless we're going to use it, eg the brlapi check
uses "if not get_option('brlapi').auto() or have_system", rbd
has a similar thing involving have_block, etc.
