Word **sigil** in name stands for latin word *sigillum*, which means **seal** or **stamp**.



### Build



Performs build with output into "build" directory. After those steps, there will be a **static and shared library** and also **selftest executable**.



```shell

cmake -E make_directory build

cmake -E chdir build cmake ..

cmake -E chdir build make

```



The selftest is run automatically during the make, but if you want to re-run it, use one of the following commands:



```shell

cmake -E chdir build make run_tests # producing default output level

cmake -E chdir build make run_tests_verbose # verbose output level

cmake -E chdir build make run_tests_quiet # without output

```
