Hello all,
in my ROS2 workspace I want to build a package which uses the catkin build system (https://github.com/fzi-forschungszentrum-informatik/Lanelet2). From the colcon documentation I take that it should be able to use catkin as underlying build system. However when I run `colcon build` on the workspace it throws the error:
CMake Error at CMakeLists.txt:4 (find_package):
By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "catkin", but
CMake did not find one.
Could not find a package configuration file provided by "catkin" with any
of the following names:
catkinConfig.cmake
catkin-config.cmake
Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set
"catkin_DIR" to a directory containing one of the above files. If "catkin"
provides a separate development package or SDK, be sure it has been
installed.
So cmake is apparently not able to "find" catkin. A `colcon info` correctly identifies the package as type: ros.catkin. If I do a catkin build in a separate catkin workspace it works. I am using Ubuntu 18.04 with both ros-melodic and ros-crystal installed from the ROS repositories. I would be thankful if you could point me in the right direction here.
