029721d69c Modernize CMake build. 
* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
  modernization measures.

* .gitignore: Add build/, as that's the example directory used in
  CMakeLists.txt.

This brings up the minimum required CMake version to 2.8.12.

The installation paths follow the GNU defaults now, e.g. installing on a
64 bit host will place binaries into the lib64/ folder on e.g. Fedora.

Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).

CMake will no longer look for a C++ compiler.

Library and .so version now match the Autotools build.

Comments in the build file and informational messages now use platform
agnostic example commands.

ftoption.h and ftconfig.h are written directly without a redundant
`-new' copy.

External dependencies are expressed as option()s and will turn up as
such in cmake-gui.

Internal: Properties such as dependencies and include directories are
now privately set on the freetype library instead of globally.

The CPack definitions have been cleaned up, the `make dist' has been
removed. Source packages generated with CPack don't contain Autotools
files and aren't used by the maintainters anyway.

On Windows, src/base/ftver.rc is compiled to decorate the library with
version and copyright information.

A pkg-config file is now generated and installed.

7109495c5e * builds/toplevel.mk (work): Use $(SEP). 
This fixes the `make refdoc' using Cygwin: $(CAT) is `type' on this
platform, and this program only understands backslashes in paths.

f4a3255d45 [unix] Use -fvisibility=hidden. 
It is now widely recommended that ELF shared libraries hide symbols
except those with explicit __attribute__((visibility("default"))).
This is supported by all major compilers and should rather be an
option in libtool.

* builds/unix/configure.raw: Add -fvisibility=hidden to CFLAGS.
* builds/unix/ftconfig.in, builds/vms/ftconfig.h,
include/freetype/config/ftconfig.h (FT_EXPORT): Use visibility
attribute.
