  <h1>Error messages</h1>
  
  <pre><code>CMake Warning at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:76 (find_package):
  Could not find a package configuration file provided by "ecl_geometry" with
  any of the following names:
  ecl_geometryConfig.cmake
  ecl_geometry-config.cmake
  
  Add the installation prefix of "ecl_geometry" to CMAKE_PREFIX_PATH or set
  "ecl_geometry_DIR" to a directory containing one of the above files.  If
  "ecl_geometry" provides a separate development package or SDK, be sure it
  has been installed.
  Call Stack (most recent call first):
  CMakeLists.txt:6 (find_package)
  
  Could not find the required component 'ecl_geometry'. The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.

  CMake Error in CMakeLists.txt:
  No cmake_minimum_required command is present.  A line of code such as
  
  cmake_minimum_required(VERSION 3.5)
  
  should be added at the top of the file.  The version specified may be lower
  if you wish to support older CMake versions for this project.  For more
  information run "cmake --help-policy CMP0000".
