Disable long-running buildsystem tests by default

[mjcarroll]

From #92, this disables several tests that take a while to run and aren't correctly detected by CMake's change-detection. This adds a new option BUILDSYSTEM_TESTING, which will re-enable these tests when true, and enables it in pipelines.

Tested locally with:

$ cmake .. -DBUILDSYSTEM_TESTING=1
$ time make
make  81.50s user 23.50s system 99% cpu 1:45.22 total

$ cmake ..
$ time make
make  0.18s user 0.07s system 99% cpu 0.254 total

Depends on gazebo-tooling/action-gz-ci#9

Note to reviewers, the action PR needs to land first, and then I will correct the branches in the workflow file and reduce it to single build with the full build invocation.

LGTM if CI passes with the action's master branch.

Also we need to look into what happened to the Jenkins builds.

Finally we should consider enabling these tests on Jenkins.

This looks like it built on a xenial machine. That doesn't seem correct, given that the minimum cmake version is way past that now.

Oh I just saw that this PR builds on top of #96 . See my comment on that PR for why we can't remove the pipelines file just yet.

Rebased and force-pushed.

Unless we get the flag turned on in jenkins, I would expect the other CI jobs to fail because there is no test output.

Ah, this will only impact Windows, because we have a test available in UNIX platforms.

[scpeters]

for Ubuntu, I think we could set the BUILDING_EXTRA_CMAKE_PARAMS variable in https://github.com/ignition-tooling/release-tools/blob/master/jenkins-scripts/docker/ign_cmake-compilation.bash

here's the cmake invocation line on windows: https://github.com/ignition-tooling/release-tools/blob/master/jenkins-scripts/lib/generic-default-devel-windows.bat#L85

[mjcarroll]

Since this passes everything but Windows, I'm going to merge. Windows CI will go green when this lands: gazebo-tooling/release-tools#210

I'd prefer to wait for the release-tools PR to land before merging this

In retrospect, I can't merge it because of the branch protection, so you'll get your wish.

windows build with gazebo-tooling/release-tools#210 https://build.osrfoundation.org/job/ignition_cmake-ci-pr_any-windows7-amd64/317/

I've cherry-picked these commits onto ign-cmake2 in disable_long_tests_2:

Can you backport to ign-cmake2?
