This may be a relatively simple fix, but I am relatively new to C++ (and am not the best at understanding the intricacies of package management) but I'm trying to install the Eigen library to use for C++ matrix multiplies/linear algebra operations. I don't really know where to put the source code and how to make the include statement not give me an error (#include errors detected. Please update your includePath. Squiggles are disabled for this translation unit). Can someone tell me a step by step process of how to make this work>
I tried placing the Eigen source code inside the same directory that my code is in, but this does not solve the issue.
