in additon to gl and sdl check, bundle also if having vulkan
This should be covered by the sdl case, anyways - vulkan display uses
sdl for window management so this usually implies that sdl display will
be present as well, unless explicitly disabled.
the previous actually didn't work properly, because uv-qt depend
on libQt6OpenGL.so.6 which in turn depend on libOpenGL.so.0. But
LD_LIBRARY_PATH is not set inside the AI so the transitive dep
is not handled and thus the preload is not applied.
Querying libQt6OpenGL.so.6 directly also don't work because it resolves
to the libOpenGL.so.0 in the same library, from which we cannot deduce
if its counterpart is inside the system.
Currently Ubuntu 25.10 live DVD (ubuntu-25.10-desktop-amd64.iso)
does not include the library, preventing the GUI from being
run. On the other hand, if used unconditionally, it causes
the warning (even in the U25.10) for which it was removed:
<https://github.com/linuxdeploy/linuxdeploy/issues/152>
So preload the library if is in the system and use the bundled just as
a fallback.
This simplifies things a bit at the expense that the soundfont is always
included/installed (91 kB).
Added get_data_path() function for generic handling the path to common
data (eg. /usr/local/share/ultragrid if installed). The idea is to catch
all cases - installed (run with absolute or relative path) or run from
inside the source directory in one place.
In CI, the attempt to download mkappimage sometimes fail with some cryptic:
```
ERROR 403: Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature..
```
ilibpipewire-0.3.so.0 was added to excludelist causing the distcheck fail,
see [1]
We do not need to exclude the lib, because we already handle the preload
in data/scripts/Linux-AppImage/AppRun:282 (the case is similar as for
libjack.so.0 as also mentioned in the related AppImage issue).

Do not bundle SDL_SOUNDFONT instead of the SoundFont now included in
sources. This is a bit contra-intuitive, since the user may have set
the SDL_SOUNDFONT for its primary reason. Using the variable was just
a workaround to find _any_ usable soundfont, which is now unneeded.
Also, the user-selected soundfont may have hundreds of MB (as usually
the general-purpose soundfonts have).
The size is only some 90 kB when compressed so it is perhaps not worth
downloading from external source and depend on it.
It could be even bundled directly, not by CI. Now it is actually the case
in Linux (create-appimage.sh) but it is also possible for other platforms.
+ removed the subshell
The redirection is actually no longer neeeded - we do not need to bother
where the output goes but the reason for the redirection is no longer
valid - the created AppImage is no longer outputted.
mkappimage now tries to automatically upload the asset if it detects
running in GitHub CI, which is not the behavior we perhaps want because
it deletes and recreates our _continuous_ release.
See following failed run:
https://github.com/CESNET/UltraGrid/actions/runs/5575039257/jobs/10185765784
+ fixed `wget` presence check in `create-appimage.sh`
Don't use bundled Wayland libraries when running on Wayland but use it
otherwise to satisfy possibly unsatisfied dependencies.
See also previous commit - Wayland libraries seem not to be portable and
prevent SDL2 native run on Wayland. After this change, SDL2 runs on
U22.04 in Weston (without Xwayland).
Keep appimageupdatetool copy in current directory (where the script also
looks it up from previous commit) as a cache.
+ use either wget or curl (whichever available)
cache/preload AppImage tools appimageupdatetool and mkappimage
Lookup the tools also in current directory where it is downloaded if
there isn't a system one, so this can be considered also as a cache for
future runs.
extract mkappimage if fuse is not available, eg. in docker containers
+ use curl instead of wget - curl is already used a line above so it
must be present, wget don't
The pattern in output of ldd that should be skipped is actually '<lib>
=> not found'. The pattern "found" of course covers that but is a little
bit misleading.
This effectively reverts 3c9b8293.
libjack.so.0 is a dependency also for different modules like portaudio
so if we do not want to depend on instance in the system, we must ship
our version.
