Hi,
it doesn't look like you're doing anything wrong. I'm definitely not
an expert in linker flags, options and outputs though.
I don't know what to look for to find out why that is linking
successfully anyway even though it does not link to libB.
The only thing I was looking for was the linker invocation which shows
that the executable is linked to libC but not libB.
Does any cmake developer have any idea how this could happen?
Thanks,
Steve.
