Package: cmake
Version: 2.8.2-2
Severity: normal
A line like this in CMakeLists.txt causes cmake on squeeze to fail:
FIND_PACKAGE(VTK 5.4 REQUIRED)
it won't find VTK although installed. In contrast, this one works fine:
FIND_PACKAGE(VTK REQUIRED)
both versions work on lenny (tested cmake 2.6-patch 4) -- although the
version requirement seems to have no effect (always succeeds with any
VTK).
Here is what I see on squeeze:
mich...@meiner /tmp % mkdir cmake_vtk/
mich...@meiner /tmp/cmake_vtk % rm -rf *; echo "FIND_PACKAGE(VTK 5.4 REQUIRED)"
> CMakeLists.txt; cmake .
...
CMake Error at /usr/share/cmake-2.8/Modules/FindVTK.cmake:136 (MESSAGE):
VTK not found. Set the VTK_DIR cmake cache entry to the directory
containing VTKConfig.cmake. This is either the root of the build tree, or
PREFIX/lib/vtk for an installation.
Call Stack (most recent call first):
CMakeLists.txt:1 (FIND_PACKAGE)
...
-- Configuring incomplete, errors occurred!
mich...@meiner /tmp/cmake_vtk % rm -rf *; echo "FIND_PACKAGE(VTK 5.4 REQUIRED)"
> CMakeLists.txt; cmake . -DVTK_DIR=/usr/lib/vtk-5.4
[SAME OUTPUT]
despite:
mich...@meiner /tmp/cmake_vtk % ls /usr/lib/vtk-5.4/VTKConfig.cmake
/usr/lib/vtk-5.4/VTKConfig.cmake
and strangely:
mich...@meiner /tmp/cmake_vtk % grep VTK_DIR CMakeCache.txt
VTK_DIR:PATH=VTK_DIR-NOTFOUND
finally:
mich...@meiner /tmp/cmake_vtk % rm -rf *; echo "FIND_PACKAGE(VTK REQUIRED)" >
CMakeLists.txt; cmake .
...
-- Configuring done
-- Generating done
-- Build files have been written to: /tmp/cmake_vtk
mich...@meiner /tmp/cmake_vtk % grep VTK_DIR CMakeCache.txt
VTK_DIR:PATH=/usr/lib/vtk-5.4
I guess either the documentation of find_package is wrong or something
is broken.
Thanks for your consideration,
Michael

Hello Michael,
that's not a bug, but expected behaviour, therefore I'm closing this bug. For
reference I partly quote FindVTK.cmake's header here:
> # The following cache entries must be set by the user to locate VTK:
> # VTK_DIR - The directory containing VTKConfig.cmake.
> # This is either the root of the build tree,
> # or the lib/vtk directory. This is the
> # only cache entry.
One could argue whether this is a good way but any request to change
FindVTK.cmake's behaviour (that is: work (again) without VTK_DIR set) should be
made upstream at [0].
Kind regards,
Kai Wasserbäch
