@andresinmp The night was too short but I dove right in this morning after I got up. At least with a clear head - good thing too, since I'm running into problems - mostly solved (missing but optional modules that I'e now installed) but finally running into te same problem (at build time) that Debian's Darktable version was having at runtime. So now I'm looking if/how I can disable an option - which involves learning a bit of learning about how cmake works :-/ - compiling a non-trivial program is such fun! NOT. (I went through countless hoops with Hugin before). #coffee now, then continue trouble shooting, I think I can probably get it to work...
