[Cmb-users] automoc symbol issues

[Haocheng Liu]

Hi TJ,

I  did some simple tests on Kerbin(windows10 + VS2015). By simply removing
**#include "pqComponentsModule.h"** and **PQCOMPONENTS_EXPORT** in
pqSMTKInfoPanel.h, the build succeeds.

It seems that PQCOMPONENTS_EXPORT is used in ParView to export model
pqComponents symbol, may I ask why we need it in CMB?
