How to use

We use the awesome spdlog library for logging as a git submodule under the deps directory. To use it in your project, just include spdlog.props in a .vcxproj like this:

<Import Project="..\..\..\deps\spdlog.props" />

It'll add the required include dirs and link the library binary itself. You can see many example usage of the library in its repository or in the bootstrapper project.
