Mentioning the version number isn't always necessary so I removed
some instances of the version number to prevent us redoing this work
for new major releases going forward.
In a few places I left references to the old name where appropriate.
There are also many CMake references to "OSX" that we have to keep
using since CMake does not offer alternative names for those variables
and target properties.
Windows uses a mechanism known as 'resource files' which provides, among
other things, metadata to a given executable/dll/driver/etc, and add a
layer of polish to a project which it would otherwise lack.
This grew out of my work creating an sfml port for macports, but should
be helpful for package maintainers of various distributions:
* add an SFML_USE_SYSTEM_DEPS option to ignore everything in extlibs/
except for headers/stb_image, and use the system versions
* install pkg-config files if a pkg-config program is found
and either lib/pkgconfig or libdata/pkgconfig exists under the
INSTALL_PREFIX, or the SFML_INSTALL_PKGCONFIG_FILES flag is set
explicitly
* install pkg-config files for static libs too, add the necessary
Requires.private and Libs.private entries to the .pc files to support
static linking
* on OS X, honor all INSTALL_NAME and RPATH related cmake variables and
only set the INSTALL_NAME_DIR to "@rpath" if none of them is set, this
preserves the default behavior of using @rpath but also allows
overriding by the usual cmake mechanisms
- The installation paths are no longer hard coded; cmake now configures them so that Frameworks and libs can be installed somewhere else.
- No longer copy sndfile.framework but instead copy the new dependencies of the audio module.
- No longer copy .DS_Store to the install directory.
Since the @loader_path was replaced with @rpath, to correctly load
binaries from within a bundle app we need to add the Frameworks
subdirectory to the run path list.
