Error in building

[Jimmy Notron]

hello
im wondering if i can ask question

im trying to build rtabmap from source exactly like official instructions but at the last when im typing "catkin_make" command i face with this error:


#################################################################################################


CMake Error at rtabmap_ros/CMakeLists.txt:21 (find_package):
  By not providing "FindRTABMap.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "RTABMap", but
  CMake did not find one.

  Could not find a package configuration file provided by "RTABMap"
  (requested version 0.11.8) with any of the following names:

    RTABMapConfig.cmake
    rtabmap-config.cmake

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


-- Configuring incomplete, errors occurred!
See also "/home/Jimmy/catkin_ws/build/CMakeFiles/CMakeOutput.log".
See also "/home/Jimmy/catkin_ws/build/CMakeFiles/CMakeError.log".
Invoking "cmake" failed

You are missing the step 2.

Thank you for your reply
i did every thing exactly based on instruction
i can fix it by using : cmake --DCMAKE_INSTALL_PREFIX=~/catkin_ws/devel in rtabmap original library ( in main dir not build folder)
but in next step (when running catkin_make command ) i get new error :
