General / Unresolved External Symbol in VS17 using CMAKE

« on: February 23, 2017, 05:25:52 am »

So I looked up almost all the posts about this error, however I still can't quite figure it out. I do not know CMAKE very well, but need to salvage a project by someone else quite a while back. Now I understand how to link properly (including statically, which is what I am trying to do now) through the project properties. However, this is cmake so I don't actually know what the problem is. Since I was familiar with VS, I decided to try to do this using the new cmake component in VS17. Currently I believe I'm having one of two issues, but I'm having difficulties pinning it down. It is either my compiled SFML libraries for VS17 isn't correct, or my CMakeLists.txt isn't correct. Would someone mind look at my CMakeLists to see if there's any problems with it?
