* Examples are no longer built on all travis images
* Coverage is no longer collected from all travis images
* Valgrind is no longer used with all travis images
This should greatly reduce the amount of compiling, downloading
binaries and general work the common images do.
* Every Linux build tracks coverage when running Debug mode
* OS X not supported yet (Future WIP)
* Our own unit tests, non-default reporters and Clara are ignored
- Added new compilers and OS X images
- Option to run SelfTest under Valgrind
- Merge "Debug" and "Release" configurations into one run
-- This saves apt setup and cmake download step per compiler, 60-90s
- Fix C++14 compilation under Clang 3.8 and up
* Removed ccache (it was slowing down the compilation for some reason)
* Enabled some C++11 builds (gcc 4.8, gcc 6, clang 3.8 for now)
* Added gcc 4.4, 4.7 and clang 3.4
The cmake download was failing, so we were relying on the old cmake,
which I broke recently (in 7ae96c710b).
Now the download should work again.
Also fixed warning that the requested OSX image no longer exists and
that it is automatically substituted for xcode 7.3 image.
Adding several improvements, such as:
- making use of the container based infrastructure
- using ccache for faster building
- builds for linux, osx
- builds for verious gcc, clang versions
- recent cmake installation
