[ITK Community] How to recompile only one module

[Michka Popoff]

I am still not able to do it.

The command make help gives me the list, so that's ok.

If I modify code in the source directory (putting some wrong stuff to break the compilation), for example in :
/Modules/Filtering/ImageGrid/include/itkTileImageFilter.h or .hxx
And then I used make like this : make ITKImageGrid-all (at the root of the build dir) or make in the module dir itself, and I get :

Built target ITKImageGrid-all

Does not seem to me that make detected something has changed. I can even delete the files from the source dir, make does not complain.
I tried with make clean && make, no difference.

If I do the same operation on a VTK build, which has a similar structure, it works and make detects the changes.
