set( MODULE_NAME mymodule )
in CMakeLists.txt (in the up-to-date master at https://github.com/nest/nest-extension-module), the module can be compiled, but nest.Import (of NEST compiled from the up-to-date master) fails with a dynamic loader error.
Maybe someone has already made extension modules after the refactoring (of 2023) of the template?
Sorry for bothering,
Best wishes,
Alex Serenko
