[Digikam-users] problem compiling 4.4.0

[Wybo]

running bootstrap.linus in trusty I got stuck with:

  CMake Error at /usr/local/share/OpenCV/OpenCVModules.cmake:117 (message):
   The imported target "opencv_core" references the file

      "/usr/local/lib/libopencv_core.so.2.4.9"

   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/local/share/OpenCV/OpenCVModules.cmake"

   but not all the files it references.

Call Stack (most recent call first):
   /usr/local/share/OpenCV/OpenCVConfig.cmake:49 (include)
   extra/libkface/cmake/modules/MacroOpenCV.cmake:27 (FIND_PACKAGE)
   extra/libkface/CMakeLists.txt:50 (DETECT_OPENCV)

See also "/home/wybo/Downloads/digikam-4.4.0/build/CMakeFiles/CMakeError.log".

The latter says:

/usr/bin/ld: cannot find -lpthreads
collect2: error: ld returned 1 exit status

What am I missing?
