Hi @lcpt .

when I want to compile xc on my Ubuntu 20.04 this error appears:

Hi, @ebrahimraeyat.

Yes, that's a known problem: the Ubuntu packaged version of gmsh is too old (sorry). You need to install gmsh 4.8.4 or newer. This is also a workaround to this problem.

I must instruct CMake to issue a warning about this.

Thanks. If I install gmsh with pip, must be there an issue?

I think pip installs only the python modules. You need the C++ headers.
