[cmake-developers] COMPILE_OPTIONS or COMPILE_FLAGS

[Harry Mallon]

Thanks Brad,

I think I can use FLAGS for now then, but if my requirements get more complicated I'll use OPTIONS and require 3.11. I think the docs change would be helpful.

Cheers,
Harry

    COMPILE_OPTIONS for targets has existed for a long time.  What is
    new in 3.11 is COMPILE_OPTIONS for source files.  COMPILE_FLAGS
    has existed for source files for a long time too.

    The difference is that COMPILE_FLAGS takes a command-line string
    of flags that requires manual escaping.  COMPILE_OPTIONS takes a
    ;-list of flags and will do the escaping automatically.

    The docs of the two options should be updated to mention each other
    and make the distinction clear.
