[vtk-developers] find_package(vtk) not supporting version anymore

[Simon Drouin]

Hi All,

It seems the recent changes in vtk-config.cmake have dropped support for
specifying a version when calling find_package( vtk ). It this the intended
new behaviour?

See the modified c++ example from the vtk source attached. The output of
cmake (3.10.1 on macOS 10.14) is the following:

CMake Error at CMakeLists.txt:6 (find_package):
Could not find a configuration file for package "VTK" that is compatible
with requested version "8.90.0".

The following configuration files were considered but not accepted:

/Users/simon/ibis/vtk-git/build-deb-qt-5.9.7-osx-10.10/vtk-config.cmake,
version: unknown


cmake doesn't seem to be able to determine the version now.
