the usage problem of occt7.5

I had compiled the occt7.5 by cmake and vs2017 in window 10. There is no problem when I compile the Occt7.5.  However, when I run the program written by occt7.5 and qt in the vs2017, the vs throwed the error. The vs cannot find the locate the program input point, such as these calsses: Quantity_Color/Ncollection_Vec3/Quantity_typeofColor.  Is there a conflict between the old version and new version? How can I solve it?
