Inconsistent detection of Python version in CMake and pybind11

The functions ``find_package(PythonInterp)`` and ``find_package(PythonLibs)`` provided by CMake

for Python version detection are not used by pybind11 due to unreliability and limitations that make

them unsuitable for pybind11's needs. Instead pybind provides its own, more reliable Python detection

will detect Python 3.x for pybind11 and may crash on

|

|

It is advised to avoid using ``find_package(PythonInterp)`` and ``find_package(PythonLibs)`` from CMake and rely
|
||||
on pybind11 in detecting Python version. If this is not possible CMake machinery should be called *before* including pybind11.
|
||||
There are three possible solutions:
|
||||
|
||||
1. Avoid using ``find_package(PythonInterp)`` and ``find_package(PythonLibs)``
|
||||
from CMake and rely on pybind11 in detecting Python version. If this is not
|
||||
possible, the CMake machinery should be called *before* including pybind11.
|
||||
2. Set ``PYBIND11_FINDPYTHON`` to ``True`` or use ``find_package(Python
|
||||
COMPONENTS Interpreter Development)`` on modern CMake (3.12+, 3.15+ better,
|
||||
3.18.2+ best). Pybind11 in these cases uses the new CMake FindPython instead
|
||||
of the old, deprecated search tools, and these modules are much better at
|
||||
finding the correct Python.
|
||||
3. Set ``PYBIND11_NOPYTHON`` to ``TRUE``. Pybind11 will not search for Python.
|
||||
However, you will have to use the target-based system, and do more setup
|
||||
yourself, because it does not know about or include things that depend on
|
||||
Python, like ``pybind11_add_module``. This might be ideal for integrating
|
||||
into an existing system, like scikit-build's Python helpers.
