Adding Eigen library to Qt Creator
-
I am new to Qt and I have a project I am working on and need to add external headers, that is the Eigen library for matrices. How can I do this. Someone give me a step by step procedure. Remember I am new

Read http://doc.qt.io/qtcreator/creator-project-qmake-libraries.html (but ignore the section on "Example of Adding Internal Libraries"). Let us know if something is unclear.

The two-step procedure in the link should be accessible to newcomers.

I use Eigen on a daily basis, there's no real setting up to use it - it's a template library, meaning only headers. You only add its location to the
INCLUDEPATHvariable in your project file and you're good to go (see @JKSH's link and here). Since I use linux and I already have eigen in my system path, I don't even do that step, I just code.PS.
A piece of advice for after you get it working:
Don't useautowith Eigen! People have been bitten by it, and there's even a dedicated page in the docs why.
