[BUG] zed_nodelets: Cannot locate rosdep definition for [zed_interfaces]

[joseandres94]

Describe the bug Hello, Today, I decided to remove the catkin_ws and build it again. I was following the steps from (https://www.stereolabs.com/docs/ros/) to install zed-ros-wrapper again. After cloning the git repository, I ran rosdep install --from-paths src --ignore-src -r -y and this error appeared:

ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: zed_nodelets: Cannot locate rosdep definition for [zed_interfaces] Continuing to install resolvable dependencies...

All required rosdeps installed successfully

I ignored this error and I ran catkin_make -DCMAKE_BUILD_TYPE=Release, and then it appeared:

-- Could NOT find zed_interfaces (missing: zed_interfaces_DIR) -- Could not find the required component 'zed_interfaces'. 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/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package): Could not find a package configuration file provided by "zed_interfaces" with any of the following names:

zed_interfacesConfig.cmake
zed_interfaces-config.cmake

Add the installation prefix of "zed_interfaces" to CMAKE_PREFIX_PATH or set "zed_interfaces_DIR" to a directory containing one of the above files. If "zed_interfaces" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): zed-ros-wrapper/zed_nodelets/CMakeLists.txt:41 (find_package)

-- Configuring incomplete, errors occurred! See also "/home/isa/catkin_ws/build/CMakeFiles/CMakeOutput.log". See also "/home/isa/catkin_ws/build/CMakeFiles/CMakeError.log". Makefile:320: recipe for target 'cmake_check_build_system' failed make: *** [cmake_check_build_system] Error 1 Invoking "make cmake_check_build_system" failed

And I am not able to continue. Today I've followed the same steps that I did a time ago and then no error appeared, but now I've found this error and I have done the same process.

Could you please tell me how to fix it?

I've seen that some days ago you updated the zed_nodelets, zed_ros_interfaces, etc. Maybe this could produce this error.

Hi @joseandres15 please follow the updated instructions, giving attention to this: git clone --recursive https://github.com/stereolabs/zed-ros-wrapper.git If you have just cloned the repository without using the --recursive flag, then you can follow the update instructions

It worked, thank you!
