Could not find rotors_descriptionConfig.cmake

[Street-wang]

Hi!
When I run catkin build, the first 20 packages are going well. However, when starting the 21th package 'rpg_quadrotor_integration_test ', I met the flowing error:

Errors << rpg_quadrotor_integration_test:cmake /home/wang/rpg_ws/logs/rpg_quadrotor_integration_test/build.cmake.003.log
CMake Error at /home/wang/rpg_ws/devel/share/catkin_simple/cmake/catkin_simple-extras.cmake:38 (find_package):
By not providing "Findrotors_description.cmake" in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
"rotors_description", but CMake did not find one.

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

rotors_descriptionConfig.cmake
rotors_description-config.cmake

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