I use the same source files to compile by setting
TARGET_INCLUDE_DIRECTORIES for two similar targets. The included
Python.h provides the PY_MAJOR_VERSION macro to know if you are
compiling for python 2 or 3.

https://github.com/devsim/devsim/blob/master/src/pythonapi/PythonCommands.cc
I avoid using FIND_PACKAGE, and code my own PYTHON or PYTHON3 variables,
like:
PYTHON_INCLUDE
PYTHON3_INCLUDE
in a specific cmake file for my configuration:

Hi,
I am trying to find a good way to compile a python module for a c++
library using boost-python for both python2 and python3 in the same
compilation. So far, The only solution I found for using
The headers CMake needs to find are different depending on the selected
version, because the CPython API changed between 2 and 3. The ABI is
also not guaranteed to be stable within 3.x minor versions unless you
set Py_LIMITED_API (see e.g.
https://stackoverflow.com/questions/28830653/build-boost-with-multiple-python-versions).
FIND_PACKAGE(PythonInterp REQUIRED)
FIND_PACKAGE(PythonLibs REQUIRED)
FIND_PACKAGE(Boost REQUIRED COMPONENTS python # or python3)
with different python versions is to use one CMakeLists.txt per
python version, each in a subdirectory, and with almost equal
contents. I would appreciate suggestions for a better approach, with
less duplication.
Best regards,
