(core): recursive sight projects inclusion does not work properly
Description
Actually, the only missing piece is that depending libraries of modules are not found in the LD_LIBRARY_PATH when we run applications from the build directory (with packaged applications there is no issue). So I reused an unused slot we add in the past for external libraries, and I just renamed the CMake variable to make it clearer. It will be defined in the intermediate repository.
See #716 (closed)
How to test it?
- Run an application depending on three repositories from its build directory.
