Basing your application on MeshLib

• C++ First of all you should make main function like this

  #include <MRMesh/MRLog.h>
  #include <MRMesh/MRSystem.h>
  #include <MRViewer/MRSetupViewer.h>
  #include <MRViewer/MRViewer.h>
   
  int main( int argc, char** argv )
  {
      MR::setupLoggerByDefault();
   
      // Init the viewer
   
      MR::Viewer::LaunchParams launchParams{ .argc = argc, .argv = argv };
      MR::Viewer::parseLaunchParams( launchParams );
      launchParams.name = "Your app name";
   
      MR::ViewerSetup viewerSetup;
      viewerSetup.setupBasePlugins( MR::Viewer::instance() );
      viewerSetup.setupCommonModifiers( MR::Viewer::instance() );
      viewerSetup.setupCommonPlugins( MR::Viewer::instance() );
      viewerSetup.setupSettingsManager( MR::Viewer::instance(), launchParams.name );
      viewerSetup.setupConfiguration( MR::Viewer::instance() );
   
      return MR::launchDefaultViewer( launchParams, viewerSetup );
  }

  Then you should make your plugins, to find how have a look at State Plugins Overview page
