Linux and Windows images now come with pre-installed Boost 1.69.
Since it is not possible to remove GIL headers from it, we should
prefer our deployment of Boost.
References:
* #276
* C/C++: Add the latest 4 versions of Boost 1.66.0 - 1.69.0 (Linux, Windows)
Microsoft/azure-pipelines-image-generation#732
* Document available versions of Boost 1.66.0 - 1.69.0 following #732 update
Microsoft/azure-pipelines-image-generation#845
* Install latest CMake and Python on VS 2015 image.
* Remove libs/gil from installed Boost 1.68 to ensure GIL headers
from the release are not accidentally used
Configuration summary:
- Linux (GCC 5.4), Windows (VS2017), Mac OS (clang 4.0)
- Boost 1.68 built with variant=release
- Boost.GIL built and tested using CMake w/ CMAKE_BUILD_TYPE=Release
- Basic setup of GIL IO extension dependencies is in place,
using .deb packages or Conan.
- Build without GIL IO extension tests due to issues in CMake
configuration, not related to Azure Pipelines.
