Enforce levelization in libxrpl with CMake #5111
Conversation
Define each "module" of libxrpl as a separate OBJECT library in CMake. Link each one only to modules of a lower level. Then link all of them into libxrpl itself.

I think this is probably not needed ?

actually, upon some testing, this whole target_include_directories seem to be not needed.

It's not needed now that all of the subdirectories in libxrpl are modules. It was necessary as I migrated them one-by-one, and it could be necessary in the future if someone adds a non-module subdirectory. Could be nice if it "just works" without tampering with the CMake. What do you think?

Perhaps comment out and put a comment above, to explain why this is not necessary and in what condition it might become necessary again ?

I like how you moved Given we already specialize both |

Makes sense. All the more reason to make an effort moving parts of |
Adds two CMake functions:
add_module(library subdirectory): Declares anOBJECT"library" (a CMake abstraction for a collection of object files) with sources from the given subdirectory of the given library, representing a module. Isolates the module's headers by creating a subdirectory in the build directory, e.g..build/tmp123, that contains just a symlink, e.g..build/tmp123/basics, to the module's header directory,e.g. include/xrpl/basics, in the source directory, and putting.build/tmp123(but notinclude/xrpl) on the include path of the module sources. This prevents the module sources from including headers not explicitly linked to the module in CMake withtarget_link_libraries.target_link_modules(library scope modules...): Links the library target to each of the module targets, and removes their sources from its source list (so they are not compiled and linked twice).Uses these functions to separate and explicitly link modules in libxrpl:
