+# - Find a VTK installation or build tree.
+# The following variables are set if VTK is found.  If VTK is not
+# found, VTK_FOUND is set to false.
+#  VTK_FOUND         - Set to true when VTK is found.
+#  VTK_USE_FILE      - CMake file to use VTK.
+#  VTK_MAJOR_VERSION - The VTK major version number.
+#  VTK_MINOR_VERSION - The VTK minor version number
+#                       (odd non-release).
+#  VTK_BUILD_VERSION - The VTK patch level
+#                       (meaningless for odd minor).
+#  VTK_INCLUDE_DIRS  - Include directories for VTK
+#  VTK_LIBRARY_DIRS  - Link directories for VTK libraries
+#  VTK_KITS          - List of VTK kits, in CAPS
+#                      (COMMON,IO,) etc.
+#  VTK_LANGUAGES     - List of wrapped languages, in CAPS
+#                      (TCL, PYHTON,) etc.
+# The following cache entries must be set by the user to locate VTK:
+#  VTK_DIR  - The directory containing VTKConfig.cmake.
+#             This is either the root of the build tree,
+#             or the lib/vtk directory.  This is the
+#             only cache entry.
+# The following variables are set for backward compatibility and
+# should not be used in new code:
+#  USE_VTK_FILE - The full path to the UseVTK.cmake file.
+#                 This is provided for backward
+#                 compatibility.  Use VTK_USE_FILE
+#                 instead.

Tobias, why do you have to add a FindVTK module? It's included in cmake 3.

Yesterday it somehow did not work for me. Will remove it, after checking it again.
