gazebo-config.cmake not found after Homebrew prints Reinstalling 4 broken dependents from source

[traversaro]

I am not sure if this is happening due to something in this repo, but since yesterday all the C++ projects that uses Gazebo which have GitHub Action-based CI and installed gazebo with brew install are failing with the following error:

2021-03-02T02:45:24.1357690Z CMake Error at CMakeLists.txt:49 (find_package):

2021-03-02T02:45:24.2768320Z   installed.

even if brew install osrf/simulation/gazebo11 is installed. I am not sure if this is related to this message:

For an example of failing builds:

• https://github.com/robotology/robotology-superbuild/runs/2009469519?check_suite_focus=true
• https://github.com/robotology/gazebo-yarp-plugins/runs/2004219148?check_suite_focus=true

[traversaro]

Indeed, in the successful builds there is no message "Reinstalling 4 broken dependents from source:", see https://github.com/robotology/gazebo-yarp-plugins/runs/1996417168?check_suite_focus=true .

I believe this is related to #1340

I just disabled all the broken bottles, so things should build from source for now

Thanks @scpeters , the CI jobs are working correctly now (see for example https://github.com/robotology/robotology-superbuild/actions/runs/616114431).
