# fltk_run_fluid: Run fluid to compile fluid (.fl) files
#
# Usage: fltk_run_fluid(SOURCES "FLUID_SOURCE [.. FLUID_SOURCE]")
#
# Input: The CMake variable "FL_FILES" must contain a list of input
# file names. Only names ending in ".fl" are considered and
# compiled to their ".cxx" and ".h" files which are stored
# in the current build directory.
#
# Output: "SOURCES" is used as a CMake variable name that is assigned the
# names of the compiled ".cxx" files as a ";" separated list in the
# parent scope (the caller's scope).
