**Basic Process:**
* To build, change to the root of the source code directory, and run `make`.
* The resulting executables can be found in `build/release/src` or `build/debug/src`, depending on what you're building.
* The resulting executables can be found in `build/release/bin` or `build/debug/bin`, depending on what you're building.
**Advanced options:**
* Parallel build: run `make -j<number of threads>` instead of `make`.
* Statically linked release build: run `make release-static`.
* Debug build: run `make build-debug`.
* Test suite: run `make test-release` to run tests in addition to building. Running `make test-debug` will do the same to the debug version.
* Debug build: run `make debug`.
* Test suite: run `make release-test` to run tests in addition to building. Running `make debug-test` will do the same to the debug version.
* Building with Clang: it may be possible to use Clang instead of GCC, but this may not work everywhere. To build, run `export CC=clang CXX=clang++` before running `make`.
