ok, I think there is a bug in our build script because this build failed but is marked as a success

CMake Error in src/CMakeLists.txt:
  Evaluation file to be written multiple times with different content.  This
  is generally caused by the content evaluating the configuration type,
  language, or location of object files:

   C:/Jenkins/workspace/ign_tools-ign-1-win/ws/build/ignition-tools/ign.rb


CMake Warning:

the colcon build should be fixed by gazebosim/gz-tools#65, but we should figure out why it currently is not marked as a failure

I'll open an issue for this so we can expedite the merging of this PR

a test has been added in gazebosim/gz-tools#67, so I've changed the logic to expect tests for ign-tools in b11aaa7
