# FindFLTK

Find the Fast Light Toolkit (FLTK) library

## Input Variables

By default this module will search for all of the FLTK components and add them to the `FLTK_LIBRARIES` variable. You can limit the components which get placed in `FLTK_LIBRARIES` by defining one or more of the following three options:

`FLTK_SKIP_OPENGL`

  Set to true to disable searching for the FLTK GL library

`FLTK_SKIP_FORMS`

  Set to true to disable searching for the FLTK Forms library

`FLTK_SKIP_IMAGES`

  Set to true to disable searching for the FLTK Images library

FLTK is composed also by a binary tool. You can set the following option:

`FLTK_SKIP_FLUID`

  Set to true to not look for the FLUID binary

## Result Variables

The following variables will be defined:

`FLTK_FOUND`

  True if all components not skipped were found

`FLTK_INCLUDE_DIR`

  Path to the include directory for FLTK header files

`FLTK_LIBRARIES`

  List of the FLTK libraries found

`FLTK_FLUID_EXECUTABLE`

  Path to the FLUID binary tool

`FLTK_WRAP_UI`

  True if FLUID is found, used to enable the FLTK_WRAP_UI command

## Cache Variables

The following cache variables are also available to set or use:

`FLTK_BASE_LIBRARY_RELEASE`

  The FLTK base library (optimized)

`FLTK_BASE_LIBRARY_DEBUG`

  The FLTK base library (debug)

`FLTK_GL_LIBRARY_RELEASE`

  The FLTK GL library (optimized)

`FLTK_GL_LIBRARY_DEBUG`

  The FLTK GL library (debug)

`FLTK_FORMS_LIBRARY_RELEASE`

`FLTK_IMAGES_LIBRARY_RELEASE`

  The FLTK Images protobuf library (optimized)

`FLTK_IMAGES_LIBRARY_DEBUG`
