How to Add an External C++ Library to Your Project Using the CodeLite IDE Add the path for the actual code (i.e.Note that this process will be different if you are using another IDE for C++, but the two basic steps are the same for all IDEs: Without further ado, here is the step-by-step process for adding an external C++ library to your project using the CodeLite IDE and Visual Studio IDE. I found the library named “ Eigen.” I added the library to my project in the CodeLite IDE, and I was ready to go.

Instead of writing the code from scratch, I searched the web for a linear algebra library in C++ that contained functionality for multiplying matrices.

You can think of libraries as a plugin or add-on that gives you more functionality.įor example, I wanted to write a program that is able to multiply two matrices together.

They prevent you from having to reinvent the wheel when you need to implement some desired functionality. Libraries in C++ are collections of code that someone else wrote.
