CMake Error at CMakeLists.txt:24 (find_package):
By not providing "Findgazebo_ros_pkgs.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"gazebo_ros_pkgs", but CMake did not find one.

Could not find a package configuration file provided by "gazebo_ros_pkgs"
with any of the following names:

gazebo_ros_pkgsConfig.cmake
gazebo_ros_pkgs-config.cmake

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