Comment # 6 on bug 624196 from Sid Boyce

says it needs 3.1.0 but 3.2.0 is installed.
/usr/share/OpenCV/OpenCVModules-release seems to be a mismatch.

  The imported target "opencv_core" references the file

     "/usr/lib64/libopencv_core.so.3.1.0"

  but this file does not exist.  Possible reasons include:

  * The file was deleted, renamed, or moved to another location.

  * An install or uninstall procedure did not complete successfully.

  * The installation package was faulty and contained

     "/usr/share/OpenCV/OpenCVModules.cmake"

  but not all the files it references.
