[vtk-developers] Factory issue for new VBO and VertexArray painters

[Xabi Riobe]

As a side question,
I got this message during the Configure step in CMake 2.8.12.2 when adding
my test in Rendering\OpenGL\Testing\Cxx:


Data file referenced by argument

DATA{C:/Dev/vtk-gerrit/VTK/Rendering/OpenGL/Testing/Data/Baseline/TestVBOandVertexArray.png,:}

corresponds to source tree path

Rendering/OpenGL/Testing/Data/Baseline/TestVBOandVertexArray.png

that does not exist as a file (with or without an extension)!


What produces it?
I added this line in the CMakeLists.txt file:

# For tests that actually use a vtkRenderWindow
vtk_add_test_cxx(
...
TestVBOandVertexArray.cxx          <=== line added
)

and the test is correctly inserted to vtkRenderingOpenGLCxxTests.exe
