Bug#736233: libvtk5-dev: vtk-5.8/vtkConfigure.h points to ccache on amd64

[Cyril Brulebois]

Package: libvtk5-dev
Version: 5.8.0-15
Severity: important

Hi,

while investigating the differences in amd64 and powerpc environments as
far as gdcm's build was concerned (#736172), I noticed that the amd64
version of /usr/include/vtk-5.8/vtkConfigure.h points to a c++ compiler
under the ccache directory:
| #define VTK_CXX_COMPILER "/usr/lib/ccache/c++"

(I'm going to assume that's only the case with the maintainer-uploaded
amd64 binaries, I didn't check across all architectures.)

I'm not sure how much that is used, but since there's no ccache
dependency I suspect stuff using it might break. So filing this as
important for now.

Mraw,
KiBi.
