Built vtk and qt together with no errors twice. When creating my own project I get this ironic error:

When trying to use a vtkQt example, CMake can never find vtk, even when correctly pointing to its dir with: cmake -DVTK\_DIR:PATH=/home/me/vtk\_build

More information: Win10 x64 machine, using mcvs2017 generator in CMake, system paths set for qt and vtk, latest version of CMake, vtk, and Qt.

My CMake file:

The “64bit” suffix makes me think that you’re trying to build your project in 32bit mode. Could you confirm what generator and toolchain you’re selecting in `cmake-gui` and/or the command line?
