The debug packages were named with the extension ".ddeb", but due to a
bug in Artifactory, they need to have the ".deb" extension. Debug symbol
packages with ".ddeb" extensions are not indexed, and thus are not
visible in apt clients.
* Fix the issue by renaming the debug packages in the build script.
* Use GCC-11 and update GCC Conan profile.
* This software requires GCC 11 and C++20. However, reporting mode is
built with C++17.
This is a quick band-aid to fix the build. Later, it will be better to
remove this package-building code.
For context, a Debian (deb) package contains bundled software and
resources necessary for installing and managing software on a
Debian-based system, including Ubuntu and derivatives.
* use tagged containers for pkg build
* update build images
* continue to build container images in pipeline, but allow
failure (non-block)
* limit travis macos cache
* add vs2019 windows to travis
* remove xcode 9 travis build
* remove clang5/6 from CI and update min version of Clang required in
cmake
* break windows CI build into stages to reduce timeouts
* update datelib
* add if condition to travis builds to allow commit message to limit
builds by platform
