I selected the option “BUILD\_SHAREED\_LIBS”, cmake is ok, but errors appeared like this during compling:

                                       Could someone can help me?

I have solved this problem. Find and open the file: E:\shot\VTK\vtk-bin\ThirdParty\glew\vtkglew\CMakeFiles\vtkglew.dir\flag.make. Add “-minline-all-stringops” option at the end of the C\_FLAGS line. remake the project.

Fix worked for me, too. Out of curiosity, how did you figure this solution out?
