TrackerServer is a test application. You need to enable testing in CMake when you configure your OpenIGTLink build.

You need to build OpenIGTLink to get this test executable. If you don’t want to build then you can use the OpenIGTLink server in Slicer or PlusServer (in Plus Toolkit).

[SlicerIGT tutorials](http://www.slicerigt.org/wp/user-tutorial/) should help you getting started.
You may find this [Plus Toolkit tutorial](https://github.com/PerkLab/PerkLabBootcamp/blob/master/Doc/day2_2_PLUS.pptx) and the [Plus Toolkit documentation](http://perk-software.cs.queensu.ca/plus/doc/nightly/user/index.html?_ga=2.97452249.792242584.1618490237-473036458.1609520395) useful, too.
