The folowing error occured during installation KnowRob according to this instruction:

CMake Error at /home/al/ros_catkin_ws/devel_isolated/catkin/share/catkin/cmake/catkinConfig.cmake:75 (find_package):
  Could not find a package configuration file provided by "roscpp" with any
  of the following names:

    roscppConfig.cmake
    roscpp-config.cmake

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

Instalation Indigo from sources according to this tutorial on Ubuntu 14.04 was successfull. May be somehow it's related with rosjava configuration?
