geant4 definitions visibility exercise

Hello,

I'm experiencing difficulties in usage geant4 visualization module to create my application (in particular in developing independent viewer, see: https://bugzilla-geant4.kek.jp/show_bug.cgi?id=2075). I think that there is an issue related to cmake configuration and setting the c-preprocessor definitions...


When I use the option -DGEANT4_USE_QT=ON then the GEANT4_USE_OPENGL is also set to ON. Afterwards it triggers adding new definition, namely G4VIS_BUILD_OPENGL_DRIVER, which is related to the code I want to use. It's super weird, because when I use standard visualization factories (like G4OpenGLStoredQtViewer) everything works well, but when I want to create my own and inherits from G4OpenGLStoredViewer I cannot see this class definition!

I've tried to figure it out by checking the imported Geant4 definitions (in my CMakeLists.txt add_definitions(${Geant4_DEFINITIONS}) ), unfortunately I see only the following:
-- Found Define: G4_STORE_TRAJECTORY
-- Found Define: G4VERBOSE
-- Found Define: G4UI_USE
-- Found Define: G4VIS_USE
-- Found Define: G4MULTITHREADED
-- Found Define: G4UI_USE_TCSH
-- Found Define: G4INTY_USE_QT
-- Found Define: G4UI_USE_QT
-- Found Define: G4VIS_USE_OPENGLQT
-- Found Define: G4INTY_USE_XT
-- Found Define: G4VIS_USE_OPENGLX
-- Found Define: G4VIS_USE_OPENGL
-- Found Define: G4_STORE_TRAJECTORY
-- Found Define: G4VERBOSE
-- Found Define: G4UI_USE
-- Found Define: G4VIS_USE
-- Found Define: G4MULTITHREADED
-- Found Define: G4UI_USE_TCSH
-- Found Define: G4INTY_USE_QT
-- Found Define: G4UI_USE_QT
-- Found Define: G4VIS_USE_OPENGLQT
-- Found Define: G4INTY_USE_XT
-- Found Define: G4VIS_USE_OPENGLX
-- Found Define: G4VIS_USE_OPENGL
 
Is that mean that the G4VIS_BUILD_OPENGL_DRIVER is private, or sth else? You can reproduce my problem by taking the attached exercise (there is simply main and CMakeLists.txt)

I would really appreciate any suggestions how to figure it out. Am I doing wrong cmake configuration or something else?

Best regards,
