[CP2K:8099] Developers: fast build, without recompiling dependencies?

Hi Jörg,

Yes, it is possible to manually recompile individual files and re-link. But 
I would like to do as little manual work as possible. Ideally, I would just 
call make and specify a make target (e.g. nodepend) to ignore dependencies. 

I know that most makefiles are written with this option in mind (e.g. fast 
or fastbuild). Is there any way to do this in CP2K?

Cheers,
Rustam
