That means basically - the current stuff works - but is not how it should be done.
Fixes https://github.com/libsdl-org/SDL/issues/2100
- SDL_CLOCK_GETTIME now defaults to ON to match autotools build
- Add detection of float.h and Xdbe
- Fix detection of pthread_setname_np() (requires _GNU_SOURCE)
- Move SDL_USE_IME definition into SDL_config.h.cmake
This means it now works with any CMake released since 2014 instead of 2018.
This was mostly just readding some special cases, and requiring 3.11.0 only
for Windows Stores apps, which isn't unreasonable. The biggest concern is
a Linux distribution not having a recent CMake; most other places will be
manually downloading and installing their own CMake.
Fixes#4930.
This API and implementation comes from the Unreal Engine branch of SDL, which
originally called this "SDL_ConfineCursor".
Some minor cleanup and changes for consistency with the rest of SDL_video, but
there are two major changes:
1. The coordinate system has been changed so that `rect` is _window_ relative
and not _screen_ relative, making it easier to implement without having
global access to the display.
2. The UE version unset all rects when passing `NULL` as a parameter for
`window`, this has been removed as it was an unused feature anyhow.
Currently this is only implemented for X, but can be supported on Wayland and
Windows at minimum too.
SDL_config.h *can* define SDL_JOYSTICK_WGI. On builds with the Windows
10 SDK available, this allow implementing trigger rumbling on Xbox One
controllers. The files included in the Visual Studio Solution in
VisualC\SDL.sln *do* have this define set.
fix#4859
This cmake is 3 years old, but it removes confusion about the CFLAGS
environment variable (as of CMake 3.10.0, reference PR #4681) and also
consolidates resolves the need to have a separate requirement for Windows
Store apps (which requires CMake 3.11.0).
CMake has standard means of setting compiler flags, such as the
-DCMAKE_C_FLAGS command line for general-purpose flags, and
-DCMAKE_BUILD_TYPE for letting it choose reasonable release/debug/etc
defaults. Trying to emulate the configure script is incorrect and confusing
here.
Fixes#1819.
Vista and later provide the SleepConditionVariableCS() function for this.
Since SDL_syscond_srw.c doesn't require SRW locks anymore, rename it to
SDL_syscond_cv.c which better reflects the implementation of condition
variables rather than the implementation of mutexes.
Fixes#4051.
