This is already a TODO in the ebuild, but I think it's good having a bug to subscribe to.
There's also the possibility of bundling lua-5.2 until it's unmasked as a system package.

I managed to get lua working with darktable using a slotted lua and a dirty hack in ebuild, as I failed to do it properly ( see this discussion https://redmine.darktable.org/issues/11641 ) I've unmasked and installed lua 5.2, eselected it, then dt compiled and lua seems to work, at least few scripts I tested yet. If somebody is able to improve my hack to make cmake to correctly pass the -isystem parameter, we'll have a decent solution...
Created attachment 475936 [details] darktable 2.2.5 ebuild with lua enabled
UPDATE to my comment #3 The issue appeared to reside in lua5.2.pc file (see link to the discussion in my previous post). It reads Cflags: -I${includedir} instead of Cflags: -I${includedir}/${lib_name_include} So far I fixed it manually, but I ought to file a bug about it. So here comes the working ebuild.
Apparently there is a bug about this already for about a year... Ohh... https://bugs.gentoo.org/show_bug.cgi?id=592052
Still waiting for lua-5.2.
For the record, current versions of darktable require lua-5.3+.

Fortunately it turns out that recent versions of Darktable come with bundled Lua 5.3 which can optionally be used instead of system version.
