The code for this recipe is available at https://github.com/dev-cafe/cmake-cookbook/tree/v1.0/chapter-02/recipe-06 and has a C++ example. The recipe is valid with CMake version 3.5 (and higher) and has been tested on GNU/Linux, macOS, and Windows.
The vector capabilities of modern processor architectures can dramatically enhance the performance of your code. This is particularly the case for certain classes of operations, and linear algebra is foremost among these. This recipe will show how to enable vectorization to speed up a simple executable using the Eigen C++ library for linear algebra.
