Hi @DrawZeroPoint
I'm having an issue building on master with catkin_make:

If the files are there and the repo is properly cloned, I assume the make order matters and you could try to first make hope by catkin_make --pkg hope

Solved, I correctly cloned the hope package using:
git submodule init
and
git submodule update

Then ran catkin_make, twice, and it worked
