CMake failed if I have installed the different version VTK #4926
Description
Describe the error
CMake failed if I have installed the different version VTK.
To Reproduce
I have installed VTK-9.0 already, then I installed pcl-1.11.1(VTK-8.2). It was failed in CMake when I want to link pcl into my project. I looked into this and find pcl can't overwrite VTK_DIR which has already set.
