OSX/CI: kanagram fails to build on branch frameworks

[Marko Käning]

Framework libkdeedu is installed on OSX:

----
$ ls /opt/kde/install/darwin/mavericks/clang/kf5-qt5/kde/kdeedu/libkdeedu/inst/lib/libkdeedu
LibKdeEduConfig.cmake  LibKdeEduTargets-debug.cmake  LibKdeEduTargets.cmake
----

but kanagram since 2b4646540a4ae0a461ebbac979af0189b325ed8f tries to find LibKEduVocDocument
instead which does not succeed:

---

CMake Error at CMakeLists.txt:38 (find_package):
  By not providing "FindLibKEduVocDocument.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "LibKEduVocDocument", but CMake did not find one.

  Could not find a package configuration file provided by
  "LibKEduVocDocument" with any of the following names:

    LibKEduVocDocumentConfig.cmake
    libkeduvocdocument-config.cmake

  Add the installation prefix of "LibKEduVocDocument" to CMAKE_PREFIX_PATH or
  set "LibKEduVocDocument_DIR" to a directory containing one of the above
  files.  If "LibKEduVocDocument" provides a separate development package or
  SDK, be sure it has been installed.
