This is a big commit and there are too many changes to list them all.
The main changes are:
- rename all CMake build options to 'FLTK_*'
- export library targets with namespace (prefix) 'fltk::'
- standardize shared library target names with suffix '-shared'
- set public build properties on libraries for consumers
- document library names and aliases in README.CMake.txt
- document changes in "Migrating Code from FLTK 1.3 to 1.4"
- partial backwards compatibility for old user projects
Included but not directly related changes:
- fix Windows (Visual Studio) DLL build
- add CMake function fl_debug_target() to show target properties
- don't build test programs if FLTK is a subproject
- internal: reformat CMake code: remove space before '('
Thanks to Matthias and Manolo for their help, testing, and feeback.

# 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).
