Re: [PATCH libosmocore] doxyfiles: refer paths to @srcdir@

When building out-of-srcdir, paths such as "src/gsm" will not find any source files. Since the Doxyfiles are preprocessed, we can prepend @srcdir@ to fix that.

Merged. Also applied an equivalent patch to libosmo-dsp. If anyone has created a Doxy template following the examples in libosmocore, you might want to check if that fix is required as well. Cheers, Sylvain
