How to pass cmake argument to PYBIND11_MODULE

[lzwhard]

MODEL_NAME is passed by -D in cmake, code like this:

// PYBIND11_MODULE(mpt, m) { // writing mpt directly is correct
PYBIND11_MODULE(MODEL_NAME, m) {
    m.doc() = "model python binding";

    py::class_<Model>(m, "Model")
        .def(py::init());
}

When I compile cmake DMODEL_ NAME=mpt, I got the following error:

error: pasting "pybind11_init_" and ""mpt"" does not give a valid preprocessing token
  124 | PYBIND11_MODULE(MODEL_NAME, m) {
      | ^~~~~~~~~~~~~~~
<command-line>: error: expected initializer before string constant

May I ask if there is a solution?

Thank you very much for your outstanding work.
