I checked this bug.
Because "/usr" is set to OpenCV_DIR,
/usr/share/OpenCV/OpenCVConfig.cmake file has not been read.
Moreover, when there is no /usr/OpenCVConfig.cmake, another checking
is executed, but only old opencv
corresponds.
The problem in which the check of OpenCV fails is solved by specifying
OpenCV_DIR.
I attach a patch.

But if you will apply this patch,  it becomes an error in other portions.
