Module dependencies in cmake not tracked after a module is updated

When f90 was introduced, with modules, it became an essential part of writing a large program to specify the interdependence of files within the project. Modules broke the convention that the object files could be created in any order, they require a specific order of compilation for interdependent files. Unfortunately, the mechanism to specify these interdependencies was not included in the fortran standard itself.

C++ is in a similar situation now that C++20 introduced modules. I found the following talk very relevant also to the state of Fortran:
