Zed_nav2 build fails using colcon build

By not providing “Findgrid_map_msgs.cmake” in CMAKE_MODULE_PATH this
project has asked CMake to find a package configuration file provided by
“grid_map_msgs”, but CMake did not find one.

Could not find a package configuration file provided by “grid_map_msgs”
with any of the following names:

grid_map_msgsConfig.cmake
grid_map_msgs-config.cmake

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

Hi @bart

can you please tell me what version of the zed-ros2-examples repository you are using?
zed_nav2 is a development package that was never released officially, probably it was wrongly released in a devel branch a few weeks ago, but it’s no more publicly available.

I have to be honest, I don’t know I pulled it a while ago.

Any alternatives for when I want to build a point cloud map?
Rtabmap also gives some problems. Did not get deeper into it yet.
