From some time ago, it was possible to easily embed a python interpreter and build an exe with pybind11.

This is useful for programs that are mainly C ++ or whose entry point is C / C ++.
By default, it searches the system and links with libPython found (for example, python in the conda environment for conda, etc.).
If you want to specify Python explicitly
cmake -DPYTHON_EXECUTABLE = / path / to / bin / python ... and PYTHON_EXECUTABLE.
(Lib also seems to find it based on the bin directory)
This is because pybind11 internally find_package (PythonInterp).

By the way, there are suffixes such as python3.8m, but here is the meaning of suffix.
