Unable to compile ROS2-SH on humble #178
Description
I was able to compile the ROS2-SH on a foxy based docker container, but when compiling it for humble I got the following error:
$ colcon build --cmake-args -DCMAKE_CXX_FLAGS="-include /usr/include/c++/11/limits -include /usr/include/c++/11/thread" -DIS_ROS2_DISTRO=humble
...

I understand that the script is failing to get information related to std_msgs, but those seem to be properly installed on the system:

Might this be related to Ubuntu 22 python version?
