no longer working with ip < 5.0?

[edwardhartnett]

Seems like we no longer build with the ip library less than version 5.0.

Is there any way we could notice in the cmake what version of ip we have, and still handle versions before 5.0?

@AlexanderRichert-NOAA would we just have to #ifdef the "use" commands to make this work?

[edwardhartnett]

OK, we will just live with this. ip-5.0.0 is already on WCOSS2 so it's not a difficult requirement.

Sorry I missed your previous comment-- Yes, for other developers I've been advising them to use #ifdef to accommodate older versions. For example, for sp_mod, UPP's ncep_post CMake config uses:

    if(ip_VERSION VERSION_GREATER_EQUAL 5.1)
      target_compile_definitions(${EXENAME} PRIVATE USE_SP_MOD=1)
    endif()
