I just encountered a similar linking issue in a Ubuntu 18.04 environment, with system packages `libgtest-dev` and `google-mock` installed, and with compile flag `-Wl,--no-undefined`. The problem is that [FindGMock.cmake](https://github.com/cartographer-project/cartographer/blob/105c034577220268cd28a304a185adbec46b729f/cmake/modules/FindGMock.cmake#L79) sets...

> @meyerj and @DorianScholz can you check flexbe_app@feature/install_support whether this addresses your requirements appropriately before I close this PR? Sorry, I am not using FlexBe at the moment and have...

We still cannot launch a behavior from install-space using the approach described at [Running Behaviors Without Operator](http://wiki.ros.org/flexbe/Tutorials/Running%20Behaviors%20Without%20Operator) without this patch. I assume the `be_launcher` script still tries to find Python...

One solution would be to extend #1651 and use the internal version of `boost::condition_variable` unconditionally, even if the system has Boost 1.61 or higher, and replace all checks for `BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC`...

This issue should have been fixed by #1878 and #1932 (for `melodic-devel`) and #2011 (backport to `kinetic-devel`). For Noetic the custom internal implementation of `boost::condition_variable` and the invalid definition of...

I assume [this comment](https://github.com/ros/geometry2/pull/346#issuecomment-440893011) still applies: > This looks right, but I believe it will break ABI so we'll need to evaulate whether an ABI change or memory leak is...

What is the policy of breaking the ABI on branch `noetic-devel`? If ABI breaking changes are not accepted anyway, for a good reason, then maybe I should re-submit this to...

I agree with @windelbouwman that the `NO_CMAKE_FIND_ROOT_PATH` flags should probably be removed: Without, cross-compilation or staged installation of a full workspace would work more or less out of the box,...

Just noticed that this is a duplicate of https://github.com/ros/dynamic_reconfigure/pull/151. I was still working on an older version of `melodic-devel` and built `dynamic_reconfigure` from source. But apparently the patch has not...
