A Cpp library to evaluate mathematical literal expressions dynamically
I have found many libraries that can evaluate mathematical expressions, e.g. this one: https://www.partow.net/programming/exprtk/index.html
-
Better library for evaluating math expressions stored on a String
I have used https://github.com/ArashPartow/exprtk for this task, since it is cpp we also used on IOS, however in android we changed to exp4j since it requires less space and did the same job.

What do I do if a repo only has a make file and I'm on windows?
For the specific example repo you cited, the project website also offers some preconfigured example MSVC solutions. You may find this much easier to get set up and running if using a Makefile is not a hard requirement.

How to calculate an expression that is stored in a string in C++
This ExprTk library looks promising: https://www.partow.net/programming/exprtk/index.html

A boolean logic simulator written in c++ & opengl 3.3. This is a toy project I'm currently developing to help me learn c++ & opengl. No libraries used, apart from stb_image and glad.
Now there are lots of libraries out there for expression processing as well. I would recommend exprtk: https://github.com/ArashPartow/exprtk
- library for solving equations from string?

Regular language input math operations
If your actual goal isn't to implement it yourself and you need it for something else, take a look at this library: https://github.com/ArashPartow/exprtk

Better library for evaluating math expressions stored on a String
I've already found on the internet a one called exp4j capable to do that but I'd like to know other too. What do you get used to use for solving issues like this?
-
String to mathematical expression with variables
I think this is what they’re referring to: https://github.com/fasseg/exp4j
