Hello everyone,

Again, it is Python 3.10 issue.

The package devel/extra-cmake-modules has a
file "find-modules/FindPythonModuleGeneration.cmake", and there
is a following statement in the file.

----------------------------------------------------------------------
if (NOT GPB_PYTHON3_LIBRARY)
  set(_PYTHON3_MIN_VERSION 4)
  set(_PYTHON3_MAX_VERSION 10)

  _find_python(3 ${_PYTHON3_MAX_VERSION}) # Canary check

  if (GPB_PYTHON3_LIBRARY)
    message(FATAL_ERROR "The max python version in
${CMAKE_FIND_PACKAGE_NAME} must be updated.")
  endif()
----------------------------------------------------------------------

For Python 3.9 or earlier, it works fine. But, for Python 3.10,
it prevents some other packages being built successfully.

Is it a good idea to give a modification like below? Or, any
other better way?
