Externals Update, master branch (2020.12.15.)
Updated all projects to atlasexternals-2.0.93. The changes wrt. atlasexternals-2.0.92 are the following (atlasexternals@2.0.92...2.0.93):
- Made the CPack setup in AtlasCMake work with any build system generator, not just with GNU Make;
- Cleaned the CLHEP configuration, so that it would use the same build system generator that the main ATLAS project is using;
- Switched back to deep-copying imported targets in the exported CMake configurations of the ATLAS projects.
The last change was necessary to address ATLINFR-3895. Since the behaviour of WorkDir based builds changed in an unfortunate way with !39028 (merged).
