How to get rid of "Unresolved external symbol" in CMake?

Question

C++ / C#

I had a repository that I did not visit for 1 month, approximately. The project in it was written in C ++ & OpenGL (GLFW and GLEW). Today I accepted the last changes (which are not there, in general, just a habit) and after building the project with cmake, it simply stopped running, giving the error "Unresolved external symbol". Moreover, this is on all commits that were earlier, and not just now. Previously, this was not at all. I am attaching a screenshot below.

Answer 1

Linker tools error LNK2001
There is a reference to something (function, variable, label) in the code that cannot be found by the linker in libraries or object files.
Forgot to register the path to the libraries in the project or development environment.
