With a recent cmake (3.31.2), I run into the following:

Code: 
CMake Warning (dev) at cmake/OpenCVUtils.cmake:144 (find_package):
  Policy CMP0148 is not set: The FindPythonInterp and FindPythonLibs modules
  are removed.  Run "cmake --help-policy CMP0148" for policy details.  Use
  the cmake_policy command to set the policy and suppress this warning.

Call Stack (most recent call first):
  cmake/OpenCVDetectPython.cmake:64 (find_host_package)
  cmake/OpenCVDetectPython.cmake:286 (find_python)
  CMakeLists.txt:660 (include)
This warning is for project developers.  Use -Wno-dev to suppress it.

-- Found PythonInterp: /usr/local/bin/python3.11 (found suitable version "3.11.11", minimum required is "3.2")

-- Could NOT find PythonLibs (missing: PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is exact version "3.11.11")

I wonder how this port could ever be built with current cmake?
 
To be able to proceed with my portmaster -a, I just disabled Python support in opencv.
Still puzzling how it is supposed to work.
