When using Cmake, the source direction /apriltag does not contain a CMakeLists.txt file. about apriltools

I think using specifically git --recursive clone https://github.com/thegoodhen/AprilTools, with --recursive, will solve the issue

Hey man. I just downloaded apriltools and ran into the same problem. I'm not sure if you got help already but I thought I'd mention how I fixed the problem just in case. The apriltag directory was downloaded without files in it. So what I ended up doing was clicking on the apriltag directory found at this link:
https://github.com/AprilRobotics/apriltag/tree/43ca2c4db31e685dcecb928d5f5ae7659677e98b

Once you download those files all you need to do is drop them into the apriltag directory and then running the cmake command will no longer give an error. I just did it and it's now working working for me. Good luck I hope that helps!
