Hello again,

**is there an option to turn on/off only some module tests?**

Example: I would like to test itkOptimizer and nothing else but the CMake option `BUILD_TESTING` turn on all tests of all modules. Therefore, I have many new projects in the solution which slows the IDE down.

**If the test creation behavior different in remote modules?**

Hello @Gordian

To run tests just for the _ITKOptimizer_ module, specify the _ITKOptimizer_ label to ctest:

```auto
ctest -L ITKOptimizer

```

The same can be done for remote modules. Or, a remote module can be built outside the build tree (externally), in which case only its tests will be available.

HTH,  
Matt

Hello @matt.mccormick,

Thank you for your help.

Considering this and the other question I had about updating remote modules, I decided to make RTK an external module for easier building and testing.

One question remain about the visibility of header in a VS solution (This seems to be the same for ITK and RTK since the later is an remote module of the former). For RTK there is another project called RTK-all that contains the header fiiles. The header files for the ITKCudaCommon project are hidden.

**How do I put the ITKCudaCommon headers in such a project?**

I guess there is a cmake option but I havent figured out which one.

With kind regards,  
Gordian

To make a list of headers visible in Visual Studio IDE, the headers need to be added to some target in the same way as sources. I guess that’s not done for `ITKCudaCommon`. To accomplish that, you will need to modify `ITKCudaCommon`'s CMake code.
