CMake error: ItkVtkGlue

Question

I built VTK-8.0.0 (using msvc2017_64) and ITK-4.12.0 (using msvc2017_64). During the ITK-build as below:

1) building VTK (CMake3.9.0)

2) building ITK (CMake3.9.0): Module_ITKVtkGlue + VTK_DIR this path C:\VTK\8.0.0\build\msvc2017_64

3) Compiling VTK using msvc2017 (in Release mode)

4) Create a new environment variable VTK_DIR with the value C:\VTK\8.0.0\build\msvc2017_64

5) Add to the path: %VTK_DIR%\bin\Release

6) Compiling ITK using msvc2017 (in Release mode)

7) Creating a new environment variable ITK_DIR with the value C:\ITK\4.12.0\build\msvc2017_64

8) Add to the path: %ITK_DIR%\bin\Release

And now, I only want to build and compile a very simple project from the link below: https://itk.org/Wiki/ITK/Examples/IO/ImageToVTKImageFilter

however, I can't configure the project getting the error below in CMake:

To solve this problem, at first, I tried to add an Entry with ItkVtkGlue path but the same error was achieved. Then, I created ItkVtkGlue.lib individually and added added a new environment variable ItkVtkGlue_DIR with the value C:\ItkVtkGlue\build\Release and also added to the path and again creating an Entry for ItkVtkGlue, but I got the same error.

I would appreciate any help... Deeply looking forward to your advice ...

Create a new environment variable VTK_DIR with the value 'C:\VTK\8.0.0\build\msvc2017_64' - When set path variables for CMake, do not use backslash in them, use forward slash instead: C:/VTK/8.0.0/build/msvc2017_64. — Tsyvarev

First of all, thanks, I did it, again the same error. please have a look at ibb.co/cZNr9k *** just a kind reminder, when building an individual itk or vtk project, it goes well, but in the case of itk+vtk, I got such an error... — ir0098
File /ITK/4.12.0/build/msvc2017_64/lib/cmake/ITK-4.12/Modules/IT‌KVtkGlue.cmake is not an error log. This is a normal file, but its content depends on your machine (more precise, it depends on installation of VTK). — Tsyvarev
You were right, the problem was about the VTK address in the IKVtkGlue.cmake. In fact, the VTK_DIR was set to "C:\VTK\8.0.0\build\msvc2017_64". II changed to set(VTK_DIR "C:/VTK/8.0.0/build/msvc2017_64") and it works now. Thanks Tsyvarev for your guides. — ir0098

The issue went back to the VTK_DIR which was defined by "\". First, I tried to replace all "\" in my environment variable VTK_DIR with "/" but it resulted in the same error. Then I defined VTK_DIR as an Entry in CMake and a path with "/" was dedicated, again the same error. In fact the problem was due to the ITKVtkGlue.cmake. The VTK_DIR was set by "\" and I manually replaced them by "/", and now ITK+VTK goes well...
