@jeromecoutant Good catch.

I had a quick look, CLI 2 defines -DTARGET_xxx, but it's only useful if one expects a given target and wants to check if it is the current target. To get a target name without knowing, yes we miss a macro. It should be super quick to fix in CMake so I'll raise a PR later.
