[CMake] Better way than: SET(CMAKE_C_ARCHIVE_CREATE "<CMAKE_AR> my_flags ... ?

[Marc Herbert]

Hi,

1.  I found the hack below in the list's archive. However it seems...
hackish. Among others it can't _append_ a flag, it can only replace all
flags. Any newer and better way to append some extra flags?

2. Bonus question: how would you query "ar" and append some extra flags
*only* when ar/ranlib are new enough to support them?

Thanks in advance,

Marc

SET(CMAKE_C_ARCHIVE_CREATE "<CMAKE_AR> -qcD <TARGET> <LINK_FLAGS>
<OBJECTS>")
SET(CMAKE_C_ARCHIVE_FINISH "<CMAKE_RANLIB> -D <TARGET>")
