    I have a project that looks like -

    root
|
|- CMakeList.txt
|- Project_A <- shared object
|  `- CMakeList.txt
`- Project_B <- actual app
   `- CMakeList.txt

    Now, Project_B depends on Project_A. Project_A builds the a shared object - libProject_A_x86_64.so, but on Ubuntu, libProject_A_x86_64.so is not being generated. On windows it works fine.

    I have a cmake configuration something like this:

    ...
target_include_directories(cook-ui-modular-qt PUBLIC
    ../Project_A
)
if(UNIX AND NOT ANDROID)
    target_link_libraries(cook-ui-modular-qt PUBLIC
        ${CMAKE_CURRENT_BINARY_DIR}/../Project_A/libProject_A.so.1
    )
endif()
...

    And this is the error I get:

    13:56:04: Running steps for project cook-ui-modular-qt...
13:56:04: Starting: "/opt/Qt/Tools/CMake/bin/cmake" --build /home/akshay/Code/build-cook-ui-modular-qt-Desktop_Qt_6_2_2_GCC_64bit-Debug --target all

      Use add_library(...) in your 'projectA' instead of qt_add_executable(...).

        You should link against the target you build, not against the created library. -> target_link_libraries(cook-ui-modular-qt PUBLIC Project_A)
        Also target_include_libraries(cook-ui-modular-qt PUBLIC ../Project_A) is wrong here. This has to be defined for Project_A so cmake can automatically add this include path when the library is used.

          @Christian-Ehrlicher I get this error now:

          /home/akshay/Code/cook-ui-modular-qt/App/Project_B/CMakeLists.txt:156: error: Target "Project_A" of type EXECUTABLE may not be linked into another target.  One may link only to INTERFACE, OBJECT, STATIC or SHARED libraries, or to executables with the ENABLE_EXPORTS property set.

            I don't know what I should add to the error message - you can not link an executable to another executable. You can only link a library to an executable.
