[vtkusers] compilation of VTK6.1 with Qt5-enabled - Policy CMP0040 is not set....

[Gib Bogle]

They look to me like warnings, not errors.  Is the build successful?

Subject: [vtkusers] compilation of VTK6.1 with Qt5-enabled - Policy CMP0040 is not set....

I am compiling VTK 6.1 from [1] with Qt enabled (Qt 5.3.2 from [2]) using cmake 3.0.2 from [3]. My OS is Ubuntu 12.04.

I am running the following command [4] for ccmake:

cd /path/to/VTK-Release-build
ccmake -DVTK_QT_VERSION:STRING=5 \
      -DQT_QMAKE_EXECUTABLE:PATH=/path/to/qt5.2.1-install/5.2.1/gcc_64/bin/qmake \
      -DVTK_Group_Qt:BOOL=ON \
      -DCMAKE_PREFIX_PATH:PATH=/path/to/qt.5.2.1-install/5.2.1/gcc_64/lib/cmake  \
      -DBUILD_SHARED_LIBS:BOOL=ON
      /path/to/VTK

but I'm getting the following error:

(ADD_CUSTOM_COMMAND):
Policy CMP0040 is not set: The target in the TARGET signature of
add_custom_command() must exist.  Run "cmake --help-policy CMP0040" for policy details.  Use the cmake_policy command to set the policy and
suppress this warning.

The target name
"/home/torabi/local2/VTK/VTK-6.1.0-build/ThirdParty/hdf5/vtkhdf5/H5Edefin.h"
is unknown in this context.
This warning is for project developers.  Use -Wno-dev to suppress it.

Would you please hint me how to tackle this error?

Thanks
