-----------------------------------------------------------------------------

meson can not find wayland scanner, but it is right at
/usr/bin/wayland-scanner.

Additionally all the .pc files of wayland reside at /usr/lib/pkgconfig/.

Note that I have wayland installed via appdir-prefix at
/Programs/Wayland/1.17.0/
and then use symlinks (similar to what the program called stow does).

llvm on the other hand is installed into the prefix /usr/.

I am not sure why the meson build can find cmake and pkg-config without a
problem, but not wayland-scanner.

cmake version is: 3.14.5

Content of wayland-scanner.pc is:

prefix=/Programs/Wayland/1.17.0
exec_prefix=${prefix}
datarootdir=${prefix}/share
pkgdatadir=${datarootdir}/wayland
wayland_scanner=${exec_prefix}/bin/wayland-scanner

Name: Wayland Scanner
Description: Wayland scanner
Version: 1.17.0

I think there may be something failing but it is not stating why. If
possible it may be useful to have meson report a bit more to the
user in such an event, because "stat /usr/bin/wayland-scanner" works
fine, and the .pc file is there too, so I have no idea why meson
can not find it.
