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.
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?
