Developing libraries can be difficult, fun and interesting; an equally difficult task is testing the library and distributing it, so that other developers can use the library in their projects.  The big advantage of using libraries to accomplish certain functionalities is that libraries are already tested and optimized for various platforms.  For the libraries optimized for particular platforms, there needs to be a dispatch mechanism to select the best optimized path depending on the processor.  I have found that the build system from the Framewave library provides a good solution to accomplish this.

 Derived from the AMD Performance Library, Framewave is a free of charge, open-source collection of popular image and signal processing routines designed to accelerate application development, debugging, multi-threading and optimization on x86-class processor platforms. This library has three paths of optimized code:  a reference code (c code) path, an SSE2 code path, and an SSE3 and F10H code path. One reason I found it interesting is because it is open-source; I can go through the code, understand it, and modify it as per my requirements, plus it has a single source bundle for four operating systems (Linux®, Mac, Windows®, and Solaris operating systems).

 Framewave has a ...
