Question about modules, CMake and using modules in dll

I've spend a lot of time trying to figure out an issue of compiling the solution for my studies using the cpp 20 modules in dynamic linked library. I've got my project structure as following:

- Main soluition directory
CMakeLists.txt
-- Application directory (sources for executable)
--- headers
.h files
--- resources
some resources for project
--- src
.cpp files
-- Library directory (some classes for project)
--- includes
.h files
--- interfaces
.ixx file (the module itself)

As you can see the solution contains two folders and I've got 1 Cmake file in parent folder to compile both exe and dll from there. Thing is - as if this would work with classic header includes, it doesn't with modules as the compilation order matters now as I learned. I'm just learning and the info on how to work with modules is scarce, I couldn't find how to order up my CMake lists to make this work pure via console.

Problem is that when running cmake to build the project - it won't find the dll's .o file and fails to building linking. The dll must be compiled up front somehow.

When I open the project in VS studio I'm able to build it if I order VS to build the .dll first and THEN order to build all. Then it successfully complies everything as the files from modules are supposedly built upfront and used later.

Did anyone had any experience on how to structure the CMake file, maybe with subfolder directives and separated CMake lists, to make it run properly?

I've got a CMakeLists.txt in parent directory like this:

cmake_minimum_required(VERSION 3.14.0)
set (CMAKE_CXX_STANDARD 20)
set(CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON)

project(RaceGame)

include_directories(
        ${PROJECT_SOURCE_DIR}/RaceApp/headers
        ${PROJECT_SOURCE_DIR}/RaceApp/src
        ${PROJECT_SOURCE_DIR}/RaceLib/interfaces        
        ${PROJECT_SOURCE_DIR}/RaceLib/includes
)

link_directories(${PROJECT_SOURCE_DIR}/RaceApp/interaces)

file(GLOB Lib_SRCS
        "${PROJECT_SOURCE_DIR}/RaceLib/interfaces/*.ixx"
        "${PROJECT_SOURCE_DIR}/RaceLib/includes/*.h"
        )

file(GLOB App_SRCS
        "${PROJECT_SOURCE_DIR}/RaceApp/headers/*.h"
        "${PROJECT_SOURCE_DIR}/RaceApp/src/*.cpp"
        )
		
configure_file(${PROJECT_SOURCE_DIR}/RaceApp/resources/botnames.txt botnames.txt COPYONLY)
configure_file(${PROJECT_SOURCE_DIR}/RaceApp/resources/botcallsigns.txt botcallsigns.txt COPYONLY)

add_library(RaceLib SHARED ${Lib_SRCS} "RaceLib/includes/RaceLibExceptions.h")
add_executable(RaceGame ${App_SRCS} "RaceLib/includes/RaceLibExceptions.h")

target_link_libraries(RaceGame RaceLib)

I've been trying many different ideas but I just have not enough experience with CMake to work this out.

In the end I just switched the library to compile as STATIC library instead of SHARED. It works, tho. That's not what I wanted, but that's what I've got working.
