This is an example of a library. You may see a list of other libraries used on Rosetta Code at Category:Solutions by Library.
FLTK is free software, licensed under LGPL with an additional clause permitting static linking from applications with incompatible licenses. It includes FLUID (FLTK User Interface Designer), a graphical GUI designer that generates C++ source and header files.
FLTK uses a lightweight design and restricts itself to GUI functionality. Because of this, the library is very small (the FLTK "Hello World" program is around 100 KiB), and is usually statically linked. It also avoids complicated macros and separate code preprocessors, and does not use advanced C++ features.
