Failed buliding on Fedora

[Dov Grobgeld]

I tried following the instructions in the README.md to compile OCP Fedora 38 but it failed as follows:

pywrap -i /usr/include/clang -l /usr/lib64/libclang.so all ocp.toml

pywrap was installed from git with commitid = f3bcde7

ocp was cloned from git and compilation was tried with commit id = 4b98a5d

If you want to just build OCP (i.e. not per se generate it), you can simply use the generated sources https://github.com/CadQuery/OCP/releases/tag/7.7.2.0

IDK what exactly is going wrong, but likely libclang has a wrong version, cf https://github.com/CadQuery/OCP/blob/master/environment.devenv.yml
