This message is expected, it is one of the result of the system introspection tests performed during configuration. This message was reported while attempting to check if the `pthread.h` header is available on the system. As expected on Windows using Visual Studio, it indicates it is not available.

Now reading the posts (especially [loadable module to integrate a haptic device - #6 by leo](https://discourse.slicer.org/t/loadable-module-to-integrate-a-haptic-device/24332/6)), I am not able to clearly understand what is the actual error. Considering that Visual Studio parallelized the build, I suspect it was displayed earlier in the log.

To move forward, it would be great to provide:

- Version of `Slicer` and `SlicerIMSTK` used
- Commands used to configure and build `Slicer` and `SlicerIMSTK` (e.g is it a Release or Debug) build
- Configuration or build error(s) reported

I suggest the following use at least Slicer `v5.0.3`. Once we sort out the issue reported on the Dashboard (link above as well as [Windows preview build failing yesterday and today](https://discourse.slicer.org/t/windows-preview-build-failing-yesterday-and-today/24567)), using the latest version would be sensible too.
