Mac-Mini 2018  
OSX 10.14.15  
XCode 10.2.1  
VTK Latest git pull origin master

I tried to build Examples/Tutorial/Step1/Cxx but Cmake Configure fails with:  
CMake Error at CMakeLists.txt:7 (vtk\_module\_config):  
Unknown CMake command “vtk\_module\_config”.

In fact, all examples I have tried to build fail with this error.

Some of the examples have been unloved (and untested) for a long time. I left those that are still using VTK 8’s CMake API with an `UNMAINTAINED.md` file. The examples without those have been updated. See `Examples/CMakeLists.txt` for the examples which are up-to-date.

I am using Win 10 64bit + VS2017 + VTK9.0.1.

There is no `UNMAINTAINED.md` file under Examples/Tutorial/Step1/Cxx, but still gives this error:

`Looking for pthread.h - not found

Found Threads: TRUE

Found OpenGL: opengl32 found components: OpenGL

CMake Error at CMakeLists.txt:5 (vtk\_module\_load):

Unknown CMake command “vtk\_module\_load”.`
