Hi, thanks for this awesome work first!
But I'm very new to the AprilTag things, could you provide some information about how to fetch the necessary cpp libraries for this project? I mean, I'm confused where to download them, the version requirements etc.
I've tried to colcon build this project but got the CMake Error like this:

-- Found sensor_msgs: 2.2.4 (/opt/ros/galactic/share/sensor_msgs/cmake)
CMake Error at CMakeLists.txt:15 (find_package):
  By not providing "Findapriltag_msgs.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "apriltag_msgs", but CMake did not find one.

  Could not find a package configuration file provided by "apriltag_msgs"
  with any of the following names:

    apriltag_msgsConfig.cmake
    apriltag_msgs-config.cmake

  Add the installation prefix of "apriltag_msgs" to CMAKE_PREFIX_PATH or set
  "apriltag_msgs_DIR" to a directory containing one of the above files.  If
  "apriltag_msgs" provides a separate development package or SDK, be sure it
  has been installed.


-- Configuring incomplete, errors occurred!

Thanks!
