CoastalApp will be deprecated. Please switch to https://github.com/oceanmodeling/ufs-coastal . CoastalApp is a NUOPC application implemented following UFS best practices to couple coastal ocean models and other domains (Sea Ice, Atmosphere, Wave, Inland Hydrology, ...)
On a gnu system (platform conda), there is a warning about a missing Include directory.
When I look this up in the code
${LIBDIR}is not defined (but what does it have to do with includes ...?)
