Wrong install path

[kaajo]

In the build_information.txt there is install path /usr/local but all .deb packages install libraries to /usr path. This leads to the wrong configuration in CMake using pkg-config. I had to manually fix the issue in my scripts using this command: sed -i 's/prefix=\/usr\/local/prefix=\/usr/' /usr/lib/pkgconfig/opencv4.pc

I suggest editing the build configuration to /usr and reupload packages

Anyway, these deb packages helped me a lot in my RPI project!
