build fails

[samuparta]

When I type the $ make command I get this error, did anybody resolved it?

I get the same issue. Did anyone find a solution?

Edit: I believe I found the solution.
The build is looking for the opencv.pc file in /usr/local/lib/pkgconfig/ directory, when it actually contains the opencv4.pc file.
This is because the file changed name with the update from OpenCV3 to OpenCV4.
Run the following command to get it to build correctly:
cp /usr/local/lib/pkgconfig/opencv4.pc /usr/local/lib/pkgconfig/opencv.pc

On Ubnutu 22, /usr/local/lib/pkgconfig/opencv.pc or /usr/local/lib/pkgconfig/opencv4.pc was not there by default, it was present in /usr/lib/x86_64-linux-gnu/pkgconfig/, just copied it to the above location and it worked.
