Building for many platforms is hard

Choosing the right libraries for your application is just one step in making it run on multiple operating systems. ForcePAD uses CMake to build the application on multiple platforms. CMake is an excellent tool that generates build files for each platform. On Windows it generates Visual Studio solution files. On other platform it generates make files. I started implementing most of the tooling for ForcePAD on Windows thinking that most of this can be easily transferred to macOS. This what not that easy. I will go through the setup in the following sections.

A new backend for ForcePAD

The current version of ForcePAD is implemented using the FLTK library and OpenGL for graphics. At the time FLTK provided an easy way of implementing an multiplatform application that could run on Windows and Unix/Linux. FLTK provided both an intuitive environment for designing the 2D user interface as well as easy OpenGL context creation. OpenGL context creation on Windows and Unix was implemented very differently on each platform. Having just one way of this enabled ForcePAD to be implemented in a single code base.
