Did you execute ./get_repos.sh?
Try to clear the CMake cache.

@dsponer was your issue resolved?

[dsponer]

@adamdbrw, Yes, I solved the problem

I did the following

1. Removed my ROS2
2. Installed ros-foxy-base
3. I downloaded the package from the foxy_fixes_for_custom_messages branch
   These steps allowed me to solve the problem
   Thank you for your help
