How to link in CMake with a dynamic library from a submodule?

Question

Programming

Hello everyone, I have
the following problem. There is a project that is built by cmake, its structure is something like this:
add_subdirectory(foo_lib) // a dynamic library is built here
add_subdirectory(foo_app) // an application is built here that uses foo_lib
in foo_app, the library is linked like this:
target_link_libraries(foo_app ... foo_lib)
And here, if foo_lib is built into a static lib, then everything works correctly, but in the case when it is a dynamic library, when building foo_app, the linker falls with undefined reference for methods from foo_lib.
Has anyone come across something similar and perhaps know how to correctly handle the paths for dynamic libraries that are built within the same project?
Thanks in advance.
