I'd prefer a runtime switch to a compile time one. 

+
+class HelloWindow : public SkOSWindow {
+public:
+    HelloWindow(void* hWnd, int argc, char** argv);
+    ~HelloWindow();
+
+    void setupBackend();
+
+protected:
+    virtual void draw(SkCanvas* canvas);
+
+    SkCanvas* createCanvas() SK_OVERRIDE;
+
+    SkColor fBGColor;
+private:
+    SkScalar fRotationAngle;
+
+#ifdef SK_HelloSkia_ENABLE_GPU
+    GrContext* fContext;
+    GrRenderTarget* fRenderTarget;
+    GrGLInterface* fInterface;
+#endif
+
+    typedef SkOSWindow INHERITED;
+};
+  #endif
