Note. the notes about git submodule init and git submodule update fail because there is no .gitmodules files in the repo
It looks as if you have failed to clone the submodules. I thought we had a CMake check for that.
according to my older directory on debian12, there is a file called .gitmodules However .gitmodules is not present in your git repo. So even if it want to clone it doesnt know from where. So I followed the path as described in the readme and downloaded the tar file for the submodule and put it in place. I saw the cmake check error but that one went away once the files where placed there. However the include path apparently doesn not include the subdirectory somehow.

Ah, yes, we stopped using submodules. We now either use the systemwide installation or use FetchContent to download it. Unfortunately, your report elides all of the CMake output, which is the bit that I'd need to be able to tell what's gone wrong for you.
yes that made it work...

Please can you share the output from cmake? Without it, we should have downloaded the robin map.
My suspicion is that the issue here isn't that robin map wasn't downloaded, but rather that it's only linked with the objc target:
https://github.com/gnustep/libobjc2/blob/7a5114deff221c58b19ce2b18245ab13aac33295/CMakeLists.txt#L288
and not with the objc-static target (which actually uses robin map):
https://github.com/gnustep/libobjc2/blob/7a5114deff221c58b19ce2b18245ab13aac33295/CMakeLists.txt#L299-L306
Also, it appears objc-static isn't linked with BlocksRuntime either, which means the EMBEDDED_BLOCKS_RUNTIME param will have no effect. Is this intentional?
