Improve recognition of Wayland and X11 specific build options and
remove duplicates from required dependencies (FLTK_LDLIBS) used in
fltk-config.
This should also fix the GitLab CI build process.
To do: the logic to find the dependencies of Wayland and X11 is
currently suboptimal. This will be improved in a later commit.

- GitHub CI: fix wrong CMake option name
- fl_add_library: disable debug output (MSVC), fix formatting
|
|
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.

... with cmake_minimum_required(VERSION 3.4) or higher. This version
sets CMP0065 to 'NEW' which by default inhibits exporting global
symbols from executable programs.
For details see CMake policy CMP0065 and README.Wayland.txt.

This library is no longer needed in FLTK itself. There is only one
demo program (test/forms.cxx) that uses it if it is built. The demo
program displays a message if fltk_forms is not available.
The default is 'enabled' for backwards compatibility but this may
be changed to 'disabled' in a future version.

1. 'exec_program()' should be replaced with 'execute_process()'. Done.
2. 'cmake -E remove' is broken and deprecated since 3.17, hence we use
'cmake -E rm' (!) for CMake since 3.17 and
'cmake -E remove' only for older CMake versions.

Update Makefiles, CMakeLists.txt, improve formatting.

This commit makes the default FLTK build setting use libdecor
as packaged in Linux when the build system contains packages
libdecor-0-dev and libdecor-0-plugin-1-gtk in version ≥ 0.2.0.
Otherwise, FLTK uses the bundled version of libdecor.
This includes situations where package libdecor-0-dev is
present in an earlier version.

Selects MSVC compiler/build options known as /MT, /MTd, /MD, or /MDd.
This applies to "Visual Studio" (IDE) and "NMake Makefiles" builds.

This modifies the debug environment so demo programs linked to FLTK
DLL's can be debugged w/o copying FLTK DLL's to the build folders
of the demo programs.
This is work in progress and may be improved in a future commit but
it works as it is now for all demo programs.

Remove code that checks CMake versions lower than 3.15
|

- add CMake option 'OPTION_USE_STD'
- add configure option '--enable-use_std'
- move FL/Fl_String.H to src/Fl_String.H
- move FL/Fl_Int_Vector.H to src/Fl_Int_Vector.H
- remove Fl_String from demo program examples/callbacks.cxx
- remove Fl_Int_Vector from public header FL/Fl_Table.H
- some methods of Fl_Table are no longer inline
- add CMake option OPTION_USE_STD to allow std::string in some
selected functions and methods
Experimental, may be removed before release:
- use either Fl_Int_Vector or std::vector in Fl_Table depending
on CMake OPTION_USE_STD or configure --enable-use_std
Move all fl_filename* functions that use Fl_String to fluid
Main changes in fluid:
- add fluid_filename.h and .cxx
- include "fluid_filename.h" rather than <FL/filename.H>
Update fl_input(), fl_password() and test/ask
- add maxchar parameter to fl_input() and fl_password()
- fl_input_str() and fl_password_str() are optional and return
std::string if enabled (FLTK_USE_STD)

... so they are not inherited by consumers of the library.
Remove 'add_definitions(-DFL_LIBRARY)' from src/CMakeLists.txt
This is not necessary, see CMake/fl_add_library.cmake
Don't set obsolete property 'CLEAN_DIRECT_OUTPUT' which was removed
in CMake 2.8.0.

- remove separate libfltk_cairo to avoid cyclic dependencies, but
- keep a dummy libfltk_cairo in 1.4.0 for backwards compatibility
- move cairo/Fl_Cairo.cxx to src/Fl_Cairo.cxx
- add preliminary Cairo support for Visual Studio (MSVC)
Static linking is not affected by this change, but users building
with hand-made Makefiles will have to remove libfltk_cairo starting
with FLTK 1.4.0. The dummy library can be linked for backwards
compatibility but it will be removed later (in 1.4.x or 1.5.0).
The shared FLTK library libfltk.{so|dylib|dll|..} depends on libcairo
if and only if FLTK is built with one of the Cairo options. This has
always been the case for OPTION_CAIROEXT but is now also true if only
OPTION_CAIRO is selected, i.e. FLTK programs linked with a Cairo
enabled shared FLTK library will also be linked with libcairo. The same
is true for configure options --enable-cairo and --enable-cairoext,
respectively.
Preliminary Cairo support for MSVC now detects a Cairo installation
using the CMake variable FLTK_CAIRO_DIR which must be set by the user.
Note that this feature is temporary and may be changed in the future
for a better and more comfortable version.

CMake only: replace wrong variable names with correct ones. Affected
were all image libraries (jpeg, png) and zlib.
These variables had been renamed in an earlier commit when lots of
CMake code had been rewritten.

Autoconf syncs png and zlib configuration
Cmake png zlib selection

|
Also add Fl::option(OPTION_FNFC_USES_ZENITY)

If available, it is used on Linux regardless of the current desktop because
it offers free XDG portal integration, which means it picks the correct file
chooser on all desktops, and allows for meaningful file selection in sandbox
environments like Flatpak.

This removes the cause of this developer's message
# FIXME: This needs to be redesigned! Forcing GTK_FOUND to 0 (NO) is a bad
# FIXME: idea because there could be unwanted side effects. AlbrechtS

Also, remove hardcoded path to wayland-protocols when
CMake version ≥ 3.4

These option combinations work:
-DOPTION_APPLE_X11
-DOPTION_APPLE_X11 -DOPTION_USE_CAIRO
But
-DOPTION_APPLE_X11 -DOPTION_USE_PANGO
is not possible because homebrew doesn't provide the pangoxft package.

This is only one minor step to remove issues of some CMake options
that can cause conflicting include directories ("-I..." switches).
See implementation note in CMake/options.cmake.

This was removed unintentionally.

This variable has never been used in the code. Configure and CMake
look for a *working* libpng (HAVE_PNG) and set variable HAVE_PNG_H
if the header <png.h> can be included.
The alternative to include <libpng/png.h> is always used in the #else
clause and doesn't need its own config variable. Configure and CMake
log what they find, hence this extra variable is not necessary.

On Windows fluid.exe is a "GUI" program and does not allow console
output which can be a problem in automated builds. In Visual Studio
the fluid GUI program would pop up console windows when generating
.cxx and .h files from .fl files.
The new (additional) fluid-cmd.exe is built as console application
for users that need it and it is used in the FLTK build process on
Windows to convert the .fl files.
