# WRF CMake Build

# The way ncep has written these makes this difficult if not impossible to do...
# # External projects, run them inline but make an alias to their target as if 
# # we "built" them ourselves - useful to avoid ExternalProject_Add() + find_package() weirdness
# # Newer versions we might need to do that since g2 relies on bacio with find_package()
# add_subdirectory( bacio )
# add_subdirectory( g2    )

# # bacio v2.6.0
# add_library( bacio::bacio ALIAS bacio )

# # g2 v3.1.2
# if ( ${USE_DOUBLE} )
#   add_library( g2::g2 ALIAS g2_d )
# else()
#   add_library( g2::g2 ALIAS g2_4 )
# endif()


# Always build

# Suffice it to say everything under this is WRF-specific while also being external
