I tried to make my life a bit easier so I played with the AUR PKGBUILD for darktable-git and modified it with my needed changes.
Fortunately Github makes it quite easy to extract patch files from pull requests, by just adding .patch to the URL. So I downloaded my PRs as patch files and modified the above PKGBUILD to my needs. I changed the URL to my LibRaw tree, but this didn’t work out. So I download it separately and overwrite the files after initializing. Pointers how to overcome this are very much welcome.
I also changed the PKGBUILD to use the build.sh script as this is much faster on my end.
So to build darktable-git with R5m2 support I used the following:
