title: CMake Error at CMakeLists.txt:5 (find_package)
body: <pre><code>CMake Error at CMakeLists.txt:5 (find_package):
    By not providing "FindVTK.cmake" in CMAKE_MODULE_PATH this project has
    asked CMake to find a package configuration file provided by "VTK", but
    CMake did not find one.
  
    Could not find a package configuration file provided by "VTK" with any of
    the following names:
  
      VTKConfig.cmake
      vtk-config.cmake
  
    Add the installation prefix of "VTK" to CMAKE_PREFIX_PATH or set "VTK_DIR"
    to a directory containing one of the above files.  If "VTK" provides a
    separate development package or SDK, be sure it has been installed.
  
  
  Configuring incomplete, errors occurred!
