opencv cmake warning meanings: CMakeLists.txt:1066 (include)

Question

I am now building from source the opencv4.1.0 with cmake3.13. The cmake configuration gives a warning message saying:

CMake Warning at          


        

Answer 1

check the file cmake/OpenCVGenSetupVars.cmake

if(DEFINED __python_path)
  if(IS_ABSOLUTE "${__python_path}")
    set(OPENCV_PYTHON_DIR_RELATIVE_CMAKECONFIG "${__python_path}")
    message(WARNING "CONFIGURATION IS NOT SUPPORTED: validate setupvars script in install directory")

It seems like you have set your Python path wrong
