Bug#737153: OpenCVModules.cmake not installed, causing visp FTBFS

[Fabien Spindler]

The proposed fix 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737153 lead to an 
other error during ViSP package configuration:

CMake Error at /usr/share/OpenCV/OpenCVModules.cmake:117 (message) :
  The imported target "opencv_java" references the file
    "/usr/share/OpenCV/java/libopencv_java248.so"

  but this file does not exist.
