make lib or, if you don't have make or don't use gcc - translate the "lib" recipe into what works best for you, ie:
gcc -Wall -Werror -O2 -shared src/*/*.c -o auxilib
Either
- Build the library as a whole separately and use that
or
- Copy header(s) with implementation file(s) with needed functionality to your project
or
- Copy code from each implementation file of your choosing to your code; it does not cross-depends on other auxilib header files and is self-standing
Currently auxilib uses MIT license.
