Isn't it just the regular `ccache` package on Debian/Ubuntu which comes with those symlinks? I don't remember `industrial_ci` doing this itself. That's probably also the reason why you have to...

You mean [this comment](https://github.com/ros-industrial/industrial_ci/pull/182#discussion_r123696726): > On debian/ubuntu these symlinks get set-up automatically in /usr/lib/ccache by update-ccache-symlinks ? `update-ccache-symlinks` is run by default after package installation. Users don't need to run...

But your question basically is whether the symlinks could *not* be added to `PATH`, right? --- Btw: CMake seems to be rapidly moving towards the point [where it will include...

I don't know about *modern* CMake, but I've used ccache for the past 10 years with CMake, and have always used the symlink approach. That's anecdotal and `n == 1`,...

Good chance Clang-Tidy is causing some/most invocations not getting to `ccache`, or some other reason it's not seeding/hitting the cache. I'm not against changing how this is all used --...

I'm confused: there is nothing to setup. If you `sudo apt install ccache` on Debian/Ubuntu, it installs symlinks into `/usr/lib/ccache` (or apparently: `update-ccache-symlinks` creates them). All you need to do...

It's not a test. See: https://github.com/ros-industrial/industrial_ci/blob/d8c5c6ea76aae945d48a86f94bad992862f37580/industrial_ci/src/ci_main.sh#L40-L57 But @ipa-mdl would be able to explain it more clearly.

What about remapping the topics? Topic names as parameters is a bit of an anti-pattern.

I'd like to strongly echo @JWhitleyWork's comment. @samiamlabs: why "hide" these discussions by distributing them across many different fora?
