I want to generate document for VTK, and I turn `VTK_BUILD_DOCUMENTATION` `ON`.

The building is OK, but bug is reported when I want to install it:

```auto
107>CMake Error at Utilities/Doxygen/cmake_install.cmake:70 (file):
107> file INSTALL cannot find "D:/Program
107> Files/VTK/bin/Utilities/Doxygen/doc/html": No such file or directory.
107>Call Stack (most recent call first):
107> cmake_install.cmake:1113 (include)
107>
107>

```

`D:/Program Files/VTK/bin` is the build directory.

How to fix this bug? Any suggestion is appreciated~~~

Documentation is not built by default. You need to explicitly build the `DoxygenDoc` target manually.
