> Tho perhaps that's more of a failing of the OpenCV build script than Cmake itself? That is exactly what that is. Cmake is extremely powerful, and it lets library authors make build configuration that is quite often too flexible. Combine that with no standardized package manager for c or c++ for decades, and much cmake evolution over that time, means you encounter many different ways to solve problems. Opencv is up there for most complex cmake projects. Only behemoths like VTK, ITK, and ROS beat it in complexity of the build. Also, don't beat yourself up too much. :)
