There are also libraries (SDKs) which can be downloaded and installed. These libraries can all be built from source. All of these libraries are provided under their respective licenses.
To get it work together and enhance it, some patches are applied here and there and the gcc compiler contains a tad more hacks/enhancements.

## Building
Simply run `make all`. Also add -j to speedup the build.
In most cases you can simply run `sudo make all`. You can use `-j` to speed up the build, adjusting the value of `-j` to the number of cores you wish to use for the build process.
