cmake error the source does not appear to contain CMakeLists.txt

cmake error the source does not appear to contain CMakeLists.txt

2024/11/18 21:36:26

I'm installing opencv in ubuntu 16.04. After installing the necessary prerequisites I used the following command:-

kvs@Hunter:~/opencv_contrib$ mkdir build
kvs@Hunter:~/opencv_contrib$ cd build
kvs@Hunter:~/opencv_contrib/build$ 
kvs@Hunter:~/opencv_contrib/build$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX+/usr/local -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules -D BUILD_EXAMPLES=ON ..

but it produced an error:-

CMake Error: The source directory "/home/kvs/opencv_contrib" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

I used the command provided in the folder 'module' documentation. How do I solve it? I tried the answers here at stack-overflow and a few other question but still can't figure it out.

Project Git repository here.

Answer

You should do mkdir build and cd build while inside opencv folder, not the opencv-contrib folder. The CMakeLists.txt is there.
