I'm trying to update the cmakefile for another project that depends on OpenCV. What's a good way to identify the correct OpenCV version across multiple platforms? I just need to figure out if OpenCV 3 is available on the current machine or not. Any hints or ideas on how to do this would be useful!
Here's a summary of what I'm trying to accomplish:
- run
locate libopencv_imgcodecs | head -n 1 | wc -l
- If this command returns 0, assume OpenCV is installed (I know this is potentially a bad assumption)
- If the command returns a non-zero number, set OpenCV version to 3.
- Set the variable
OPENCV_VERSION
based on this.
I don't feel too good about running the shell command (locate, etc).. is there a better way to do this?
