Building against libsquish-dev is more or less impossible as the
pkg-config file is broken:

✗ cat /usr/lib/x86_64-linux-gnu/pkgconfig/libsquish.pc                                                                              git:(master|✚2…1
prefix=
exec_prefix=${prefix}
libdir=${prefix}/lib/x86_64-linux-gnu
sharedlibdir=${libdir}
includedir=${prefix}/include

Name: libsquish
Description: squish DXT library
Version: 1.15

Requires:
Libs: -L${libdir} -L${sharedlibdir} -lsquish
Cflags: -I${includedir}



Without a defined prefix, the include path won't be found and building
fails.
The library path kind of works due to the merged /usr, but its still
broken.
Please fix the pkg-config file, using prefix=/usr will fix the issue.

Oh dear. That's not good. libsquish.pc.in  has
prefix=@PREFIX@
in it which is clearly intended to get set during the build, but clearly it isn't.

This is almost certainly my fault for this unnecessarily complicated
implementaiton and not noticing that it wasn't actually working.

I could just fill in plain text '/usr', but the idea is that you can change the PREFIX for the build and built it so it still works in another location.
I think that's how pkgconfig files should be done?
And I'm fairly sure I copied this from some other library package, but clearly the @PREFIX@ var isn't getting set in this case.

Thanks for the report (it's taken a while for anyone to notice).

I'll give it a prod.
