[SOLVED] CMake can't find Python Development directory

CMake can't find Python Development directory

I want to install librealsense v2.50 on Jetson Xavier nx dev-kit with ubuntu 20.04 with python bindings as follows:

~/Downloads/librealsense-2.50.0/build$ cmake ../ -DFORCE_LIBUVC=true\
-DCMAKE_BUILD_TYPE=release \
-DBUILD_WITH_CUDA=true -DBUILD_PYTHON_BINDINGS=true\
-DBUILD_NODEJS_BINDINGS=true -DPYTHON_EXECUTABLE=/usr/bin/python3\
-DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true\
-DPYTHON_INCLUDE_DIR=/usr/include/python3.8 \
-DPYTHON_LIBRARY=/usr/lib/libpython3.8.so

I get the following output:

CMake Warning:
-- Checking internet connection...
-- Internet connection identified
CMake Deprecation Warning at CMakeLists.txt:9 (MESSAGE):
  FORCE_LIBUVC, FORCE_WINUSB_UVC and ANDROID_USB_HOST_UVC are deprecated, use
  FORCE_RSUSB_BACKEND instead

Then I get an error:

CMake Error at /usr/share/cmake-3.26/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find Python (missing: Python_INCLUDE_DIRS Development
  Development.Module Development.Embed) (found version "2.7.18")

I have solved this error before by removing the Development directory from the cmake find python, but I can't find it now, can you please tell me how can I solve this problem?

Solution

As a workaround I have removed the Development directory from the python wrapper cmake file and it worked for me.
