1.2.0 breaks build on openSUSE - No rule to make

[susnux]

When trying to build 1.2.0 on openSUSE it fails with error messages like this:

make[2]: *** No rule to make target 'nanopb/pb_decode.c', needed by ...

It looks like the reason is setting relative source files without specificity the DIRECTORY, so if you build out-of-tree it fails. It can be fixed with this patch:

Ok not always, even with this patch at least on some systems I got this error (full log):

Is it possible to set up github actions with opensuse? It would help verify this
