Used this to build inside release directory of opencv

To build OpenCV inside the virtual environment offersTest

cmake -D WITH_CUDA=ON -D CUDA_ARCH_BIN="5.3" -D CUDA_ARCH_PTX="" -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.0.0/modules -D WITH_GSTREAMER=ON -D WITH_LIBV4L=ON -D INSTALL_C_EXAMPLES=OFF -D BUILD_opencv_python3=ON -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF -D CMAKE_BUILD_TYPE=RELEASE -D PYTHON_EXECUTABLE=~/.virtualenvs/offersTest/bin/python3 -D CMAKE_INSTALL_PREFIX=/usr/local ..

I wanted the OpenCV to be installed inside the virtual environment offersTest as i have specified the path here

-D PYTHON_EXECUTABLE=~/.virtualenvs/offersTest/bin/python3

during make -j2 the interpreter points to the correct location of the python

But during sudo make install

It prefers the minimum python version 2.7

Please, use **text** representation for logs instead of *images* whenever possible. See also [ask]. – Tsyvarev Oct 01 '19 at 14:20
Normally, after `make` completes, `make all` doesn't re-run configuration and building steps: These steps are re-run only when CMake (or make) detects some changes. – Tsyvarev Oct 01 '19 at 14:21
How do i set the correct path? – Santhosh Dhaipule Chandrakanth Oct 01 '19 at 14:49
