CMake fails when building OpenCV (Ubuntu)
15,697
Thanks to hetepeperfan I was able to fix my problem. It turns out I was simply missing a C++ compiler.
After running sudo apt-get install build-essential and cleaning up my build folder and rerunning cmake the problem was fixed.

I'm trying to build OpenCV with CMake but when I build it, some stuff goes wrong and I have no idea what to do to fix it.
So the question basically is: How do I fix it?
