在做編譯的時候出現這種情況，
Could not find the required component 'ecl_threads'. 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 at /opt/ros/kinetic/share/catkin/cmake/catkinConfig.cmake:83 (find_package):
Could not find a package configuration file provided by "ecl_threads" with
any of the following names:
ecl_threadsConfig.cmake
ecl_threads-config.cmake
Add the installation prefix of "ecl_threads" to CMAKE_PREFIX_PATH or set
"ecl_threads_DIR" to a directory containing one of the above files. If
"ecl_threads" provides a separate development package or SDK, be sure it
has been installed.
