I suspect this is because these are C or Fortran sub-projects. I'm looking for some clean way to tell Cmake to apply externis to all the C++ only subprojects if possible. I'll see what I can come up with.
I'd also like to know, if multiple GCC commands end up pointing to the same trace.json, especially in a parallel build, will externis automagically ensure that it doesn't step over itself?

I just went ahead and tried it out :)
I can get it to work for some sub-sets of our project, but for quite a bit of it I get the following error:
cc1: error: cannot load plugin /opt/rh/gcc-toolset-13/root/usr/lib/gcc/x86_64-redhat-linux/13/plugin/externis.so: /opt/rh/gcc-toolset-13/root/usr/lib/gcc/x86_64-redhat-linux/13/plugin/externis.so: undefined symbol: _Z14decl_as_stringP9tree_nodei
