Hi,

I try to build a loadable module which need a vtkMRMLMarkupsFiducialNode. I have a linker error during the build. I think the problem is related with the following warning:

Dependent extension vtkSlicerMarkupsModuleMRML cannot be found by CMake  
find\_package(), therefore paths variables cannot be imported from this  
extension. The problem can be resolved by generating  
vtkSlicerMarkupsModuleMRMLConfig.cmake by adding  
include(${Slicer\_EXTENSION\_GENERATE\_CONFIG}) to the top-level  
CMakeLists.txt of the dependent extension.

The problem is include(${Slicer\_EXTENSION\_GENERATE\_CONFIG}) is present in the top-level CMakeLists and I cannot find any vtkSlicerMarkupsModuleMRMLConfig.cmake file. Any idea on how to solve it ?

Many thanks !

In case of a linking problem i think you must add MRMLMarkups library to the CMakeLists.txt where you want to use markup nodes:

For example if you are going to use markups in logic, then in Logic directory CMakeLists.txt

`set(${KIT}_TARGET_LIBRARIES`  
`...`  
` vtkSlicerMarkupsModuleMRML`  
`...`  
` )`
