CMake is a popular open-source, cross-platform family of tools designed to build, test, and package software.
In this lesson we will motivate the use of Make and CMake discover and apply various CMake building blocks. We will exercise applying the material by configuring and building an example mixed Fortran-C++ project using CMake.
The material is not well tested on Windows because the lesson authors are Linux/Mac people. Corrections and contributions which make the lesson more general and portable are very much welcome.
You need to install CMake, as well as Fortran, C, and C++ compilers.
To appreciate this material it helps to have some prior exposure to Makefiles and compiled languages but we have also something for the Python/R crowd.
