Comment 3 Samuel Bernardo 2019-12-15 11:59:12 UTC 
This happened after installing opencv-4.1.2-r2

It would probably help if you did not use ccache. :-\

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
configure:34451: $? = 1
configure:34465: $PKG_CONFIG --exists --print-errors "opencv > 2.0"
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
configure:34468: $? = 1
configure:34482: result: no
No package 'opencv' found
configure:34499: error: Library opencv > 2.0 needed for opencv was not found

It's looking for opencv.pc while it ought to be looking for opencv4.pc instead.
