might just be that libxml+xdmf didn't rebuild themselves when you turned on 
shared libs. Try wiping the build parts of those projects and rerunning cmake 
then build again.

Thank you all!

Turning on shared libs solved the problem for CMake. However, when I compile 
ParaView I get an error related to xdmf.dll which is not built because of 
external  linker problem:

Betreff: RE: "another target with the same name already exists" whenexecuting 
CMake for plugin project

I've had this problem too. Seems that if you forget to turn on shared libs when 
you build paraview, then the find_package stuff for paraview causes these odd 
errors when you try to build plugins. Try turning on shared libs if you didn't 
already have it enabled. If it was already, then disregard this email.

Subject: [Paraview] "another target with the same name already exists" when 
executing CMake for plugin project

I try to compile one of the example plugins (GUIView) and get the following 
error when executing CMake (2.8.6)


CMake Error at C:/ParaView-3.14.0/bin/VTK/ParaViewTargets.cmake:16 
(ADD_EXECUTABLE):

add_executable cannot create imported target "vtkEncodeString" because

another target with the same name already exists.

Call Stack (most recent call first):

C:/ParaView-3.14.0/bin/VTK/VTKConfig.cmake:244 (INCLUDE)

C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/FindVTK.cmake:73 
(FIND_PACKAGE)

C:/ParaView-3.14.0/ParaViewUse.cmake:9 (FIND_PACKAGE)

CMakeLists.txt:9 (INCLUDE)

I build Paraview (3.14.0) and QT with VS2005 successfully. I have another 
Paraview binary (3.14.0) installed on the same machine but no separate VTK 
sources.

Any idea what is going on?

Regards, Peter.
