I am new to this stuff and I have been trying to fix another issue:
Two OpenCV's are installed (with different versions) and I can't delete all traces of the past one
and I was suggested to do
cmake -D CMAKE_PREFIX_PATH = usr/local ..
which I did and cmake do not work now. When I try a simple "cmake .." I get
No current working directory
Aborted
How do I fix this? And how do I set cmake_prefix_path?
