Issue Description

I want to build librealsense 2.50.0 with python bindings from source on Jetson Xavier NX dev-kit, I have done:

~/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 output:

-- 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

-- pybind11 v2.6.2

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")

(find_package_handle_standard_args)
  wrappers/python/CMakeLists.txt:63 (find_package)

I have solved this error before by removing the Development directory from the cmake find python, can you please tell me how can I solve this problem properly? thanks in advance.

Hi @bhomaidan1990 There is a guide at https://github.com/IntelRealSense/librealsense/issues/6964#issuecomment-707501049 for installing librealsense and the Python wrapper at the same time from source code on Jetson boards. References to Python 3.6 in the instructions should be changed to the Python 3.8 version that you are using.
