[vtkusers] Building vtkGraphics with -fPIC

[Bill Lorensen]

I don't think you should be setting -fPic directory. Try building your
vtk with SHARED_LIBS ON.

I fixed it by modifying VTK/Common/CMakeLists.txt on line 546, adding -fPIC to the GET_TARGET_PROPERTY line, and had hoped to fix it the same way here, but I can't find a GET_TARGET_PROPERTY command for vtkGraphics. I've tried running ccmake and adding -fPIC to all the FLAGS variables to no avail. I also tried adding SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC") to the main CMakeLists.txt, but that also didn't seem to have an effect. Can anyone tell me how to build this with fPIC?
