in the second project that includes the library. The widgets
show up just fine, but nothing from the stylesheet is displayed.
Is there something else I'm forgetting to do?  For example, I've

SAIWIDGETSSHARED_EXPORT Frame : public QFrame {     explicit
Frame(QFrame* parent  = nullptr);     Frame(QWidget* widget,
QFrame* parent  = nullptr);      void addWidget(QWidget* value);
virtual void mouseMoveEvent(QMouseEvent *e) override;
QVBoxLayout layout;   And load the stylesheet like this...
QApplication a(argc, argv);  QFile styleFile( %path to the
stylesheet% ); styleFile.open( QFile::ReadOnly );  QString
style( styleFile.readAll() ); a.setStyleSheet(
