I am attempting to install OpenCV on my Jetson Nano following the "Get Your Jestson Nano Working" instructions in the Donkey Car instructions and when I complete the Cmake Setup instructions:

Create a build directory

cd projects/cv2/opencv

mkdir build

cd build

Setup CMake

cmake -D CMAKE_BUILD_TYPE=RELEASE \

-D CMAKE_INSTALL_PREFIX=/usr/local \

-D INSTALL_PYTHON_EXAMPLES=ON \

-D INSTALL_C_EXAMPLES=OFF \

-D OPENCV_ENABLE_NONFREE=ON \

# Contrib path
-D OPENCV_EXTRA_MODULES_PATH=~/projects/cv2/opencv_contrib/modules \

# Your virtual environment's Python executable
# You need to specify the result of echo $(which python)
-D PYTHON_EXECUTABLE=~/env/bin/python \

-D BUILD_EXAMPLES=ON ../opencv

I get a message saying "CMake Error: The source directory "/home/donkey/projects/cv2/opencv/opencv" does not exist.

Of course it does not exist because "projects/cv2/opencv/" is in the "home" directory and there is no "donkey" directory in the "home" directory. Can anyone tell me what in the Cmake Setup instructions are causing "donkey" directory and the additional "/opencv" to be inserted in the installation path? I suspect that the Cmake Setup "-D CMAKE_INSTALL_PREFIX=/usr/local \" might be causing the problem. Also "-D OPENCV_EXTRA_MODULES_PATH=~/projects/cv2/opencv_contrib/modules \" does not result in an error. Regards, TCIII
