As someone titled a compiler switch during one of my first jobs. Been looking for a way to specify commandline switches on a CMake project under VS2017? Missing Project/Properties? This is what you’re loking for : https://blogs.msdn.microsoft.com/vcblog/2016/10/05/cmake-support-in-visual-studio/#debug-code

In other news, discovered my GPS USB stick automatically adds leap seconds to GPS time. Unfortunately it only adds them up to 2015 (bought it last year). Which is logical, but a mite irritating. Would have been better if they didn’t add them at all to a certain extent.
