Unresolved External Symbol

[ghost]

Hello, just real quick thank you for this amazing repository.

I have built PolyHook in x64-Release mode and now I'm attempting to include it into my project, but whenever I attempt to build the project I get this build output:

Aditional Dependencies:
capstone.lib;asmjit.lib;polyhook_2.lib;

Project structure:

I believe that I have missed some crucial information about how to use PolyHook correctly, any help is appreciated. (If full project is needed / more information, then please tell me)

Make sure you have the latest version of visual studio, and that you've got the cmake tools support installed for visual studio. Read about that here: https://docs.microsoft.com/en-us/cpp/build/cmake-projects-in-visual-studio?view=vs-2019

Then you need to import the project as a cmake poject, you will not have to set additional dependencies and things like that, the cmake script will do all that for you. This is all documented clearly in the readme, I suggest giving that another thorough read and starting fresh.

Thank you, all issues went away as soon as i ported my source to cmake.
