I have a new build error:  
[92%] Building CXX object Modules/Remote/SkullStrip/test/CMakeFiles/SkullStripTestDriver.dir/SkullStripTestDriver.cxx.o  
In file included from /home/melrobin/packages/ITK/Modules/Core/TestKernel/include/itkTestDriverInclude.h:49:0,

#include “itkImageIOFactoryRegisterManager.h”

I know that 5.0 is still in alpha, but have I done something wrong here?

Thank you very much for the reply. I do see the pull request, but not a patch that I can apply. What should I do to apply these changes?

There is a [patch pending](http://review.source.kitware.com/#/c/23337/), but it is a better idea to build the module externally, e.g.,

```auto
git clone https://github.com/lorensen/skullStrip
mkdir skullStrip-build
cd skullStrip-build
cmake -DITK_DIR=/path/to/ITK-build ../skullStrip
make

```
