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.

|
|
# This macro displays the name and value of some CMake variables
|
|
# defined by pkg_check_modules().
|
|
#
|
|
# Syntax:
|
|
#
|
|
# fl_debug_pkg(PREFIX NAME)
|
|
#
|
|
# Example for package "cairo":
|
|
#
|
|
# pkg_check_modules (CAIRO cairo)
|
|
# fl_debug_pkg (CAIRO cairo)
|
|
#
|
|
# The first command searches for pkg 'cairo' and stores the results
|
|
# in CMake variables with prefix 'CAIRO_'.
|
|
#
|
|
# The second command displays all relevant variables if the package has
|
|
# been found, otherwise only 'CAIRO_FOUND' (empty or false).
