Colcon build issue

[Spruudis]

When building any C++ package I am presented with the following error:

CMake Error at CMakeLists.txt:10 (find_package):
  By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "ament_cmake", but CMake did not find one.

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

    ament_cmakeConfig.cmake
    ament_cmake-config.cmake

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

I have sourced the .bashrc file and made some progress in fixing the error by appending CMAKE_PREFIX_PATH with the ROS2 installation path in the CMakeLists.txt, however this has only caused further colcon build environment errors.

When running the ROS2 installation script I get

Summary: 200 packages finished [3min 42s]
  2 packages had stderr output: demo_nodes_py launch_testing_ros

Any suggestions on how I could fix this problem?

Note: I am trying to install ROS2 on the Jetson AGX Xavier
