CMake Error for noetic

Using ROS - noetic
After cloning waypoint_nav, I get the following error after running catkin_make:

I am having the same issue here. Any updates on this?
Also using ROS Noetic.

For anyone that runs into this issue in the future, here is how I got this to work on Noetic:

• in your workspace: git clone https://github.com/nickcharron/waypoint_nav.git

navigate to
/home/{user}/catkin_ws/src/waypoint_nav/hector_slam/hector_mapping_nav/CmakeLists.txt

comment out the following line as signals was removed from boost in the version noetic runs on:

find_package(Boost REQUIRED COMPONENTS thread signals)

cd ~/catkin_ws/
catkin_make

Mine built correctly, have yet to run the package yet.

Thank you very much!

No problem. @nickcharron You don't see any issues with this do you? Signals is not used in Boost 1.69+ I believe. I can create a noetic-devel branch so future noetic users don't need to do that extra step if you would like.
