Building SlicerIGT exten

in windows vs2022

CMake Error at CMakeLists.txt:25 (find_package):
  By not providing "FindSlicerIGSIO.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "SlicerIGSIO", but CMake did not find one.

Follewed the [Extensions — 3D Slicer documentation](https://development doc)

SlicerIGT has a dependency on another extension, SlicerIGSIO. So you need to build SlicerIGSIO and then you can build SlicerIGT.

That’s right, and I build the SlicerIGSIO first, and add this to cmake gui(win10), ’ SlicerIGSIO_DIR ****/SlicerIGSIO/inner-build ’

by the way, I hvae build the slicer with igt successfully, but the custom version I have built can load the other module, like “openlink” or sth else, should I build this together?
