Fix cairo build (autoconf + CMake) + README's

- rewrite to use pkg-config with both autoconf + CMake
- remove hardcoded library names
- fix build dependencies and search directories
- remove or replace old and unused variables
- update README files

To be done:
- implement fallback for autoconf/configure if pkg-config is missing
- fix pango build (uses cairo internally)

Note 1: CMake builds *require* the use of pkg-config.
Note 2: As of Feb 2021 autoconf/configure/make builds require pkg-config
as well but there are plans to implement a fallback mechanism so you can
build FLTK w/o having to install and use pkg-config. This will be done if
possible (but not guaranteed).
3.2 Windows
-----------
------------
TBD
3.3 Mac OSX
-----------
TBD
3.3 macOS
----------
As under Linux you can use both build options, i.e. autoconf/make or CMake
to build FLTK with Cairo support. One option is to install Homebrew and
add the required libraries with `brew install ...'. It is always required
to install the "Xcode commandline tools" but a full installation of Xcode
is not necessary. If you choose to use Xcode you can generate the Xcode
IDE files with CMake.
The following instructions are intentionally terse. More detailed
information can be found in README.macOS.md and README.CMake.txt.
3.3.1 Install Xcode Commandline Tools
--------------------------------------
Launch a "Terminal" and execute `xcode-select --install', then select to
install the Xcode commandline tools. This installs the required compilers
and build tools, for instance `git' (commandline only) and `clang'.
With these tools installed it is already possible to download and build
a current FLTK tarball or snapshot. All you need to do is unpack the
tarball and run `make' in the root directory. This will run `configure',
generate the necessary files, and build FLTK in its standard configuration.
Note 1: this requires an existing `configure' file which is included in
FLTK releases and snapshots but not in the FLTK Git repository.
Note 2: to build current FLTK downloaded from Git using configure + make
you need to run `autoconf' to generate 'configure'. If autoconf is not
available on your system you can download a FLTK snapshot, unpack it,
and copy the 'configure' file from the snapshot to your Git worktree.
3.3.2 Install Homebrew for Cairo and other Library Support
-----------------------------------------------------------
There are several options to install additional library support under
macOS. macOS does not provide a package manager to install such software.
This README is about installing and using Homebrew as a package manager
to build FLTK with Cairo, everything else (for instance "Fink") is beyond
the scope of this README.
This was tested on a MacBook Air 2020 (M1) with the new Apple Silicon M1
(ARM) processor.
Go to https://brew.sh/ and follow the instructions under "Install Homebrew".
Before you do this, read about the security implications - the FLTK team
is not responsible for your system security. Read their docs on how to
install and use Homebrew.
If you installed Homebrew correctly you can use `brew search cairo' or any
other software (package) name to see if it can be installed. If yes, run
`brew install cairo' (or other name) to install it.
Other helpful packages are 'autoconf' and other Unix (Linux) tools, for
instance 'git-gui' (installs 'gitk' and 'git gui' commands). The Xcode
commandline tools mentioned above install only the git commandline tool.
3.3.3 Install CMake and Build with CMake
-----------------------------------------
Either use `brew install cmake' or go to https://cmake.org/download/
and download the latest stable CMake release for macOS, for instance
'cmake-3.19.6-macos-universal.dmg' (at the time of this writing). Open
(mount) this .dmg file in the Finder. In the shown window you can either
run CMake directly or drag the CMake application to the "Applications"
folder to install it (recommended). Then you can run CMake from your
Applications folder or using "launchpad". See README.macOS.md for
instructions to install the downloaded CMake GUI tool for use with the
commandline.
Once you start the CMake GUI version you can select your source folder
(where you downloaded FLTK) and the build folder (either a subdirectory,
e.g. 'build' or another folder anywhere else) and click "configure".
Follow the instructions and select either "native compilers" or Xcode or
whatever you like to build your FLTK library. In the CMake GUI you need
to select OPTION_CAIRO (ON) to build with basic Cairo support. Finally
click "generate" to create the build files.
For more information on using CMake to build FLTK see README.CMake.txt.
