CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 2.8.12 will be removed from a future version of

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

CMake Error at /usr/share/catkin/cmake/catkinConfig.cmake:88 (find_package):
  Could not find a package configuration file provided by "tf2_eigen" with
  any of the following names:

    tf2_eigenConfig.cmake
    tf2_eigen-config.cmake

  Add the installation prefix of "tf2_eigen" to CMAKE_PREFIX_PATH or set
  "tf2_eigen_DIR" to a directory containing one of the above files.  If
  "tf2_eigen" provides a separate development package or SDK, be sure it has
  been installed.
