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
This commit fixes the FindXCB.cmake module for the case no components
are requested. The previous version assigned `XCB_FIND_COMPONENTS`
list to an empty variable name.
I was lucky enough to catch the bug in a corner case where both
`XCB_COMPONENTS` and `XCB_FIND_COMPONENTS` were empty and `set()`
command failed, but note this awesome CMake language supports more annoying
corner cases like `XCB_COMPONENTS` empty and `XCB_FIND_COMPONENTS`
with two elements, which results in the following `set()` invocation:
``` cmake
set(${XCB_FIND_COMPONENTS[0]} ${XCB_FIND_COMPONENTS[1]})
```
So always beware of CMake secret charms...
* Updated the Android toolchain file to support NDKs up to the latest release (r12b; based on https://github.com/gongminmin/android-cmake).
* Fixed missing sRGB extension defines - also SFML once again compiles for older target API levels not having the sRGB extensions (fixes#1079, supersedes #1085).
* Changed SFML's default STL runtime to `stlport_shared`, since `c++_shared` is no longer supported.
Environment variables (e.g. PATH on Windows) are looked up early by CMake, and libraries found there are prioritized over those in SFML's own folder. To avoid paths to wrong libraries, this commit modifies the CMake find_library() call, such that environment variables are no longer considered as suitable paths.
* Replaced the toolchain file with a new version based on [zuhowei's fork](https://github.com/zhuowei/android-cmake), which enables x64 builds as well as support for the latest NDK. This breaks compatibility with old build directories.
* Removed the STL dependency from **sfml-activity** rather than relying on *some* implementation implicitly linked by default.
* Deleted *project.properties*, which wasn't supposed to be part of the repository code. You have to use the Android SDK to recreate it (`android update project --path to/your/example --target 1 --name SFML-Example`).
* Made it possible to select a STL implementation to be used (default: `c++_shared`). Keep in mind that not all available configurations are necessarily compatible with SFML.
* Fixed linker flags to be compatible with Nvidia's Nsight Tegra for Visual Studio.
* It is now possible to compile the Android version using Nvidia's Nsight Tegra for Visual Studio (requires up-to-date CMake and `CMAKE_SFML_SYSTEM` to be set to `Android`; keep in mind that this is still experimental and requires further CMake updates).
* Updated and renamed some Android specific CMake variables.
* Made `armeabi-v7a` the default ABI for Android builds.
* Added FindXCB.cmake script
* Added AutoPointer wrapper for automatically free'ing pointers
* Huge commit: Ported linux implementation of sfml-window to xcb
* Xcb is now used for window creation, event loop etc
* As GLX is linked to Xlib, that part of the implementation
still uses Xlib.
* Also, some keyboard related (such as XLookupString) stuff
is still Xlib, as xcb does not have it (yet?).
* Replaced some enums with the xcb equivalents
- Replaced @executable_path by @rpath for more flexibility
- Updated freetype and sndfile libs as follow:
install_name_tool -id "@rpath/../Frameworks/freetype.framework/Versions/A/freetype" freetype
install_name_tool -id "@rpath/../Frameworks/sndfile.framework/Versions/A/sndfile" sndfile
