  By not providing "Findignition-launch3.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "ignition-launch3", but CMake did not find one.

  Could not find a package configuration file provided by "ignition-launch3"

    ignition-launch3Config.cmake
    ignition-launch3-config.cmake

  Add the installation prefix of "ignition-launch3" to CMAKE_PREFIX_PATH or
  set "ignition-launch3_DIR" to a directory containing one of the above
  files.  If "ignition-launch3" provides a separate development package or
  SDK, be sure it has been installed.
