Currently this package doesn't have maintainer. I tried your patch @wyrmku with few changes it works. Maybe you want to adopt this package and incorporate fixes?

I've created a ctranslate2 package, please test.

patch to fix git and build directory

git complains with fatal: transport 'file' not allowed unless you change it to git -c protocol.file.allow=always submodule update.

Missing submodules: third_party/ruy, third_party/ruy/third_party/cpuinfo, third_party/ruy/third_party/googletest, third_party/spdlog, third_party/thrust/dependencies/cub

Removed submodules: third_party/cub

And package() is failing since commit 55b94d3 because the build directory changed. And it installs files that conflict with nlohmann-json.

pkgver() should return an actual version number via git describe.

Since git 2.38. the git config calls now need the --global option.

Line 75 does not work. And generally makepkg will always cd into $srcdir ,so you could shorten the cd-lines.

cd ctranslate2/build

The python part should be split out of the package and put into a separate PKGBUILD depending on this one.

It's also missing a make dependency on python-setuptools.

I think the fundamental issue here is that setup.py is supposed to run after installing the main stuff built by cmake. I can get the same thing to happen if I build from source without the PKGBUILD and I don't run make install before setup.py

I was able to get it to build by making the following change to the PKGBUILD, but I don't know if it will work at runtime because it changes what path setup.py uses for the library.
