Cant build launch_testing_ament_cmake

[wscott20]

Every time I try to colcon build launch_teting_ament_cmake it keeps on saying

CMake Error at CMakeLists.txt:24 (message):
  launch_testing package not found

---
Failed   <<< launch_testing_ament_cmake [11.6s, exited with code 1]

No matter what I try it won't build it even after colcon builds and installs launch_testing

Bug report

Required Info:

• Operating System:
  • MacOS Sequoia
• Installation type:
  • source
• Version or commit hash:
  • df54d3b755e3b5fc73972f4e97b0b18a1bbc61db
• DDS implementation:
  • fastrtps/fastdds
• Client library (if applicable):
  • (trying to use rclpy but it won't build since it needs rcutils which needs launch_testing_ament_cmake)

Steps to reproduce issue

mkdir -p ros2_ws/src
cd ros2_ws
vcs import --input https://raw.githubusercontent.com/ros2/ros2/jazzy/ros2.repos src
(maybe remove unnecessary packages that arentneeded to build for rclpy and ros2cli)
colcon build
#### Expected behavior
being able to build everything and source install/setup.bash and run ros2 commands
#### Actual behavior

Starting >>> launch_testing_ament_cmake --- stderr: launch_testing_ament_cmake
CMake Error at CMakeLists.txt:24 (message): launch_testing package not found

---

Failed <<< launch_testing_ament_cmake [2.57s, exited with code 1]

#### Additional information
tried on humble and jazzy

Hi @wscott20, was this resolved by straightening out the Python/Conda issues we discussed in Discord, or is this still a problem for you?

I got it working via docker
