Using Cmake and find: Configuring incomplete, errors occurred!

I see that you installed vcpkg to a different location than where you previously had it. Did you install igraph to this new location? The error indicates that you didn’t.

See here on how to delimit code and terminal output: How to use this forum?


At this point I strongly suggest to find someone who is experienced with CMake and can sit with you at your computer and help directly. The problems you are seeing are not related to igraph. They are about basic usage of CMake and vcpkg. It is understandable that it will be overwhelming for a a newcomer to learn to use all these systems all at once, but a frequent back and forth on a forum is not a productive way of doing so.
