Hi,
I am using CMake to set up a VTK project. Our project requires VTK to be
version 7.1 or newer.
I'm using Ubuntu 16.04 with CMake 3.5.1.
My CMakeLists.txt looks like this:
cmake_minimum_required(VERSION 2.8)
project(test_vtk_versions)
find_package(VTK 7.1 REQUIRED)
include(${VTK_USE_FILE})
add_executable(test_vtk_1 test_vtk_1)
target_link_libraries(test_vtk_1 ${VTK_LIBRARIES})
I have several versions of VTK installed on my machine:
* VTK 6.2 from the Ubuntu repositories
* VTK 7.1 compiled/installed from sources
* VTK 8.0 compiled/installed from sources
$ ls /usr/local/lib/cmake/vtk* /usr/lib/cmake/vtk*
/usr/lib/cmake/vtk-6.2:
exportheader.cmake.in UseVTK.cmake
vtkJavaWrapping.cmake vtkModuleMacros.cmake VTKTargets.cmake
vtkThirdParty.cmake vtkWrapPython.sip.in
(... list was manually shortened ...)
/usr/local/lib/cmake/vtk-7.1:
FindTCL.cmake VTKConfigVersion.cmake vtkGroups.cmake
vtkModuleHeaders.cmake.in vtkObjectFactory.h.in vtkTclWrapping.cmake
vtkWrapPython.cmake
(... list was manually shortened ...)
/usr/local/lib/cmake/vtk-8.0:
FindTCL.cmake VTKConfigVersion.cmake vtkGroups.cmake
vtkModuleHeaders.cmake.in vtkObjectFactory.h.in
vtkTclTkMacros.cmake vtkWrapping.cmake
(... list was manually shortened ...)
The project can be configured (Unix Makefile) and compiled, it is compiled
against VTK 7.1 in this configuration.
However if I remove VTK 7.1 from the system (using sudo xargs rm <
"install_manifest.txt") then I end with this this error:
CMake Error at CMakeLists.txt:4 (find_package):
Could not find a configuration file for package "VTK" that is compatible
with requested version "7.1".
The following configuration files were considered but not accepted:
/usr/local/lib/cmake/vtk-8.0/VTKConfig.cmake, version: 8.0.0
/usr/lib/cmake/vtk-6.2/VTKConfig.cmake, version: 6.2.0
I have also tried find_package(VTK 7.1*.0* REQUIRED), without success.
Why isn't VTK 8.0.0 accepted? It is a greater version number so I expected it
to be ok.
How do I specify that I want VTK 7.1 OR newer?
Thank you for your time
Bye
