MOC error LNK2019 for QMetaObject when import/export

[kikijoko]

I am getting unresolved external symbols for all the parts of code where QMetaObject is used. I think its because import/export definitions.

I am generating bindings using shiboken and in my cmakelist I am using AutoGenerateHeader which is different from other examples where they add just a macro.h header that takes care of import/export. So my current problem is that the headerExport is generated and defined for can_library, but I link the can_library to a different one later one at which point i need to be using or better to say I need to redefine the exportHeader contents to switch to import if I'm thiniking correct. it has something to do with my MOC and those lines i added below, because when I take away e.g BUSINTERFACES_EXPORT="__declspec(dllexport)" I get 1 less error.

this are the errors (i am getting more but only posting 2 for better oversight):

I set my target_compile_definitions for can_library and bindings like this :

if(BUILD_SHARED_LIBS)
   target_compile_definitions(${can_library} PRIVATE
       BUSINTERFACES_EXPORT="__declspec(dllexport)"
       CANBASE_EXPORT="__declspec(dllexport)"
       CANOPEN2_EXPORT="__declspec(dllexport)"
       SOFTWARE_FRAMEWORK_EXPORT="__declspec(dllexport)"
       CANTS_EXPORT="__declspec(dllexport)"
   )
   target_compile_definitions(${bindings_library} INTERFACE
       BUSINTERFACES_EXPORT="__declspec(dllimport)"
       CANBASE_EXPORT="__declspec(dllimport)"
       CANOPEN2_EXPORT="__declspec(dllimport)"
       SOFTWARE_FRAMEWORK_EXPORT="__declspec(dllimport)"
       CANTS_EXPORT="__declspec(dllimport)"
   )
else()
   target_compile_definitions(${can_library} PRIVATE
       BUSINTERFACES_EXPORT=""
       CANBASE_EXPORT=""
       CANOPEN2_EXPORT=""
       SOFTWARE_FRAMEWORK_EXPORT=""
       CANTS_EXPORT=""
   )
   target_compile_definitions(${bindings_library} PRIVATE
       BUSINTERFACES_EXPORT=""
       CANBASE_EXPORT=""
       CANOPEN2_EXPORT=""
       SOFTWARE_FRAMEWORK_EXPORT=""
       CANTS_EXPORT=""
   )
endif()
target_link_libraries(${bindings_library} PRIVATE ${can_library})

each of those names e.g. BUSINTERFACES_EXPORT is a GenerateExportHeaders macro:

#define BUSINTERFACES_EXPORT_H

#ifdef BUSINTERFACES_BUILT_AS_STATIC
#  define BUSINTERFACES_EXPORT
#  define BUSINTERFACES_NO_EXPORT
#else
#  ifndef BUSINTERFACES_EXPORT
#    ifdef businterfaces_EXPORTS
        /* We are building this library */
#      define BUSINTERFACES_EXPORT __declspec(dllexport)
#    else
        /* We are using this library */
#      define BUSINTERFACES_EXPORT __declspec(dllimport)
#    endif
#  endif

#  ifndef BUSINTERFACES_NO_EXPORT
#    define BUSINTERFACES_NO_EXPORT 
#  endif
#endif

#ifndef BUSINTERFACES_DEPRECATED
#  define BUSINTERFACES_DEPRECATED __declspec(deprecated)
#endif

#ifndef BUSINTERFACES_DEPRECATED_EXPORT
#  define BUSINTERFACES_DEPRECATED_EXPORT BUSINTERFACES_EXPORT BUSINTERFACES_DEPRECATED
#endif

#ifndef BUSINTERFACES_DEPRECATED_NO_EXPORT
#  define BUSINTERFACES_DEPRECATED_NO_EXPORT BUSINTERFACES_NO_EXPORT BUSINTERFACES_DEPRECATED
#endif

#if 0 /* DEFINE_NO_DEPRECATED */
#  ifndef BUSINTERFACES_NO_DEPRECATED
#    define BUSINTERFACES_NO_DEPRECATED
#  endif
#endif

#endif /* BUSINTERFACES_EXPORT_H */
