Detecting compilation option and flags

Lars Christensen
I rely on these to detect options and flags:


But not all options are picked up. These are missing:

1. Debug flag (when CMAKE_BUILD_TYPE=Debug)

How can I reliably detect ALL compilation flags for a target?

Picking up these two flags is required for my pre-compiled header cmake hack[1]. It used to work OK. I guess Debug can be detected and picked up from _FLAGS_DEBUG, but I don't see a way to pick up -std=.
