While testing zint under GH scallywag (10903), cygport check ctest now

Everything worked fine for my previous zint updates up to 2025-03-01 (9484).
After adding b-r xorg-server-extra, using that package's xvfb-run (instead
of xvfb.cygclass xvfb_run) works, but now with two test failures, under
both GH scallywag (10907) and locally.
Does something need to be tweaked in xvfb_run xvfb.cygclass to have it use
or work more like xorg-server-extra xvfb-run and avoid hanging but avoid
issues?
By contrast, locally, cygport check "hangs" at end *after* running tests,
with gam_server, bash, subshell, and tee still running, where GH scallywag
hangs starting ctest.
Note that you'll need to unset DISPLAY, if it points to a local server you're
already running, to replicate what happens in the CI job - otherwise cygport
just uses the existing server...
Modified playground cygport to check for $GITHUB_WORKFLOW = scallywag and run
ctest under xvfb-run then run under xvfb_run with -xv enabled, which loops
starting an X server, running xmodmap, killing xvfb, deleting X tmp lock and
socket, incrementing xvfb_display, and repeats: see GH scallywag zint job 10923.
Well, this is odd.
I don't think there's been a change in the actual server in this timeframe.
cygport's xvfb_run function is a bit of a misnomer, since it actually runs Xorg
server with the 'dummy' driver.
I was thinking maybe some recent changes to xinit might be causing a problem,
but xvfb.cygclass actually has custom implementation of that logic, to allow it
to run a bash function (rather than just an executable) against the server.
Huh, well, looking into it a bit more, that logic looks a bit suspect:
It can loop forever if there's a problem starting the xserver, and it will
probably fail if the hardware we're running on is too fast...
I've released cygport 0.37.6, with a bit of a hack to better allow for that,
let's see if that improves anything.
Thanks Jon,
Not much of a clue about X except as a user.
Will upgrade and retry.
(As an aside, I'm a bit curious why you moved the cmake files to /usr/lib/
cmake. Unless they are arch-dependent in some way, they belong in /usr/share...)
Upstream decision - there appear to be views on this - basically import
libraries vs macros - leaving make install alone - going with that dir. ;^>
