To Reproduce Steps to reproduce the behavior: Build this package with colcon

Expected behavior No compiler warnings

Screenshots

Environment (please complete the following information):

• OS: ubuntu 22.04

Additional context I traced the problem to here: https://github.com/novatel/novatel_edie/blob/1.0.0/src/decoders/common/test/CMakeLists.txt

As novatel_edie is cloned from within this package. However the message is present in a test. Can the compilation of these tests be disabled completely by default? That would get rid of the warning message but also save compilation time for end-users.

Hi Timple. Sorry for the delayed response. We are working on this and have some changes that we are reviewing internally.

Hi Timple.

Thanks for bringing this up. We have changed the verbosity of the messages output from the tests to DEBUG. We're leaving the tests enabled by default as EDIE is part of the critical functionality for this driver so we need to be able to identify if there's issues with it.

In addition to EDIE, a couple of those error messages were generated from the CMakeLists.txt in src/novatel_oem7_driver. I have changed that on the humble branch to no longer output those messages. Those ones from your terminal are:

#31 1184.7 Cloning into 'novatel_oem7_decoder'...
#31 1184.7 HEAD is now at d02ccc2 Updating minimum cmake version to satisfy warnings on ROS2 build farm

Please let me know if this works for you and if you're still seeing any issues with regards to stderr output during standard operation of the driver.
