[CMake] Fwd: Linking GSL to cmake using command line

Hi Sachi and everyone,

Sorry, I didn't realise her original message wasn't CC'ed to the list.
Please keep replies to the list, Sachi, unless there's a good reason
you shouldn't.  It will also allow someone to jump in if I've said
something incorrectly about your problem.

Hi Sachi,

Then, to be frank, it's not something that CMake's users can help you
with.  It's (most probably) how the developer is using CMake to look
for GSL and you should be contacting him/her.  Generally, the end user
of program X shouldn't have to learn about CMake.  (Of course, no one
is stopping you from learning.)  The developer should be trying to fix
it, unless you happen to already be an expert on CMake.

If the developer isn't very responsive to your query, then that's a
separate issue, that's also not related to CMake...  S/he might be
happy to hear from you since it's a bug report and it can only make
program X better...I think?
