Installation
The latest version of GIL can be downloaded from https://github.com/boostorg/gil.
The GIL is a header-only library. Meaning, it consists of header files only, it does not require Boost to be built and it does not require any libraries to link against.
Note
The exception to dependencies-free rule of GIL is the I/O extension which requires client libraries implementing popular image formats like libpng, libjpeg, etc.
In order to use GIL, including boost/gil.hpp and telling your compiler
where to find Boost and GIL headers should be sufficient for most projects.
