Description

Updating to latest MSVC build tools breaks the build due to spdlog internal library errors.

To Reproduce

Update Visual Studio to the latest version and use the most recent build tools. When trying to build KnightOnLine project, the following errors will be produced:

Tasks

Rebuild spdlog library with SPDLOG_USE_STD_FORMAT: https://github.com/gabime/spdlog/blob/a2b4262090fd3f005c2315dcb5be2f0f1774a005/CMakeLists.txt#L90

and update ko-vendor assets.

Deliverables

• Fix spdlog compile errors ko-vendor#11 - needs to be merged first and create a new release of the repo
• Fix spdlog compile errors #217
