USING CMAKE WITH FLTK
=======================
The CMake Export/Import facility can be thought of as an automated
fltk-config. For example, if you link your program to the fltk
library, it will automatically link in all of its dependencies. This
includes any special flags. ie on Linux it includes the -lpthread flag.
This howto assumes that you have FLTK libraries which were built using
CMake, installed. Building them with CMake generates some CMake helper
files which are installed in standard locations, making FLTK easy to find

------
The set(FLTK_DIR ...) command is a superhint to the find_package command.
This is very useful if you don't install or have a non-standard install.
The find_package command tells CMake to find the package FLTK, REQUIRED
means that it is an error if it's not found. NO_MODULE tells it to search
only for the FLTKConfig file, not using the FindFLTK.cmake supplied with
CMake, which doesn't work with this version of FLTK.
Once the package is found we include the ${FLTK_USE_FILE} which adds the
FLTK include directories and library link information to its knowledge
base. After that your programs will be able to find FLTK headers and
when you link the fltk library, it automatically links the libraries
fltk depends on.

will be able to find FLTK headers.
The WIN32 in the add_executable tells your Windows compiler that this is
a gui app. It is ignored on other platforms.
