Hi all,
In one CMakeLists.txt, I have
find_package( VTK REQUIRED )
if( VTK_FOUND )
include( ${VTK_USE_FILE} )
endif()
if I provide VTK_DIR by using a relative path, it does not work (see
error message below); if I enter the full path it works.
This is the error message:
CMake Error at /opt/local/share/cmake-2.8/Modules/FindVTK.cmake:135
(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. For VTK 4.0, this is the
location of
UseVTK.cmake. This is either the root of the build tree or
PREFIX/include/vtk for an installation.
Call Stack (most recent call first):
Exercises/LevelSets/Source/CMakeLists.txt:13 (find_package)
This could have been fine and understandable if it was the same
behavior for ITK, but it's not...
i.e.
find_package( ITK REQUIRED )
if( ITK_FOUND )
include( ${ITK_USE_FILE} )
endif()
if a relative path is provided, it does work.
I use CMake 2.8.5, I build the master branch of VTK myself with the
same version of CMake...
Can someone explain to me what's the difference in between ITK and VTK
with respect to find_package? why is it working for one and not the
other one?
If relative paths are not supported, why doesn't it warn users?
Thanks,
Arnaud
