You need the target, not the library. MITK uses CMake's find_package() command for its dependencies like ITK. When you look at MITK-superbuild/ep/lib/cmake/ITK-4.13/ITKTargets.cmake, which eventually is parsed through this mechanism, you find the target "itkvnl_algo", so simply add itkvnl_algo to your module's PACKAGE_DEPENDS. However, this dependency should also be transitively available with your ITK|ITKVNL dependency. If both approaches do not work, your requested function might not be publicly available from this library, I didn't dive into the vnl code to check.

I've tried your suggestion but I still have the problem.

Unfortunately, the module code doesn't link. This is the line of code that compiles but doesn't link: vnl_gaussian_kernel_1d k(0.0); The CMakeLists: MITK_CREATE_MODULE( INCLUDE_DIRS PRIVATE src PUBLIC ${MYMODULE_INCLUDES_DIR} DEPENDS PUBLIC MitkCore MitkAnnotation PACKAGE_DEPENDS PUBLIC VTK|vtkFiltersFlowPaths ITK|ITKRegistrationCommon+ITKImageStatistics+ITKVNL OpenCV ) target_link_libraries(${MODULE_TARGET} PUBLIC ${MYMODULE_LIBRARIES}) Furthermore, when looking at the project in Visual Studio (properties->Linker->Input->Additional Dependencies), the vnl_algo lib is there. I am using the ITK from the superbuild. Best, Gwenael Sent from Outlook<http://aka.ms/weboutlook>
