C++ Redefinitions of macros and functions with 3rd party libraries

Question

I have a project which using a couple of 3rd party libraries. Among them it uses GLEW and ENet. When trying to compile the project it yields alot of errors about redefinitions of functions and macros. How can I solve this issue without changing the libraries? (I can't add namespaces to Enet because it is written in C)

Thanks in advance! Sorry for my bad english!
