OpenCV 4.0 would solve some problems on my current project, but 3.x was such a huge hassle to buid (Linux/C++) that I am hesitant to disrupt current installations. Has anyone built and run 4.0 along side an existing 3.0 version without getting into trouble?

you can choose a custom install path with cmake, like:

cmake -DCMAKE_INSTALL_PREFIX=/home/martian/opencv4

then again, you have to run ldconfig (in the bin folder) there, so your project finds the correct so's later
