Trouble recompiling Laz because of git submodule and duplicated ppu

[guest58172]

I use a package in a project. The package is a git submodule.
I also have this package as a repository, that i use to install as a design-time package.

When recompiling the project Laz complains that the PPUs exist twice, which is true, but i don't get why the PPUs generated for the project are seen by the IDE (the project isn't even opened)

For now i delete manually the lib folder of the project when i have to recompile Laz but i 'd like to know if there another way.
It's not at all obvious why and where Laz has registered the lib path of the project

Maybe the design package references the runtime package?
