------------------------------------------- HOW TO USE THE FLTK IDE ENVIRONMENTS ------------------------------------------- Since FLTK 1.4.0 we do no longer include IDE solution files in our source distribution. If you want to build the FLTK library with an IDE you need to use CMake to generate the IDE files from the source distribution. Using CMake to generate IDE project files ------------------------------------------------------------------------ IDE files can easily be created using CMake and the provided CMake files. For more info about using CMake to build FLTK please read the file README.CMake.txt in the root directory of the FLTK distribution.
