lib/README.txt -------------- This README file is a placeholder for FLTK library files on your system if FLTK is built using 'configure' and 'make'. Building FLTK with CMake If FLTK is built using CMake all static and shared libraries are created in the 'lib' subdirectory of the build tree. We strongly recommend to build with CMake outside the source tree ("out-of-tree") as described in README.CMake.txt in the root folder of the FLTK distribution. If FLTK is built out-of-tree as recommended this folder will not be touched. Building FLTK with configure + make Under UNIX/Linux and other systems that support 'configure' and 'make' (e.g. MinGW, MSYS) a single set of library files will be built, with or without debug information depending on the options you provided to the configure script. The FLTK build system based on configure does not support out-of-tree builds, hence the static libraries will be built in this 'lib' folder and the shared libraries (if enabled) can be found in the 'src' folder.
