Fix vtk interface include directories detection

- occurs since vtk (ver 9.3.20231115) with cmake 3.27.7 on Ubuntu 22.04
- seems not occuring with cmake 3.22.1 that comes with Ubuntu 22.04
- Retrieving interface include directories on any VTK component with

  get_target_property(imported_incs_ VTK::ChartsCore INTERFACE_INCLUDE_DIRECTORIES)

  lead to retrieve

  $<BUILD_INTERFACE:/home/VTK/install/include/vtk-9.3>

  instead of /home/VTK/install/include/vtk-9.3
- Here the fix consists in removing "$<BUILD_INTERFACE" and ">" strings
