You'll need to edit either E3SM/components/$component/bld/configure OR E3SM/components/$component/cime_config/buildlib_cmake and make a PR to merge your change.
Permanently change macro settings based on the presence of a component
You can parse the entire compset (as opposed to just looking at the current component) by putting something like the following in the relevant cmake macro:
| Code Block |
|---|
if ("name-of-component" IN_LIST COMP_NAMES)
# Make config change here
endif() |
This can be useful when a global change is needed based on the presence of a component. A potential use case is change the configuration of a shared lib based on the presence of a component. For example, to change the Kokkos configuration if eamxx is an active component:
| Code Block |
|---|
if ("eamxx" IN_LIST COMP_NAMES)
string(APPEND KOKKOS_OPTIONS " -DKokkos_ENABLE_OPENMP=ON")
endif() |
Permanently add compile flags for a specific file
