I have been trying to install opencv4.0.1 on ubuntu for a few weeks now. I have followed the opencv installation instructions
and I am able to make and compile the library, yet after installation, pkgconfig still cant find the library, and when I try to build programs, I get things like missing library errors.



$ pkg-config --cflags opencv
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found

  • Did you set PREFIX=/usr/local - or somewhere else (perhaps somewhere in your home directory)?
