Citra SDL2 doesn't have a launcher, and citra.desktop tries to execute
citra-qt which is N/A unless built with ENABLE_QT. Limiting installed
files to one of the options also makes it easier to split them into
separate non-conflicting packages downstream.
Most modern Unix environments use 64-bit off_t by default: OpenBSD,
FreeBSD, OS X, and Linux libc implementations such as Musl.
glibc is the lone exception; it can default to 32 bits but this is
configurable by setting _FILE_OFFSET_BITS.
Avoiding the stat64()/fstat64() interfaces is desirable because they
are nonstandard and not implemented on many systems (including
OpenBSD and FreeBSD), and using 64 bits for stat()/fstat() is either
the default or trivial to set up.
In QT 5.7 they added a new check for CXX features which appends a minimum
required standard to the CXX_FLAGS. Because we were writing the flag
directly previously, cmake assumed it needed to add a c++11 flag to the
build. This tells cmake to use c++14 on every build.
This option makes the generated binary crash with an illegal
instruction when the target CPU doesn’t support the SSE4.1 extension
(see #1968), with no noticeable performance increase compared to a
generic build.
This requires bumping up to a minimum of CMake 3.1. The benefit
of using the imported target is that you can switch to the -pthread
compiler flag on request, which may be necessary for some systems if
available.
citra: Remove GLFW, Add SDL2
FindSDL2: Do not CACHE SDL2_* variables if library is not found
EmuWindow_SDL2: Set minimal client area at initialisation time
EmuWindow_SDL2: Corrections
EmuWindow_SDL2: Fix no decorations on startup on OS X
cmake: windows_copy_files
The `option` commands have been moved to the top of the file, so that
the relevant options are registered in the CMake cache even if one of
the required libraries is not found. This solves an ergonomic problem
when using bundled libraries where you have to first download GLFW
before being able to select the option to also download Qt.
Using this variable is problematic is the user has several versions of
Qt installed on their system. There is no way to know ahead of time if
the Qt version pointed to by QTDIR matches the toolchain that is being
targeted.
The Qt installation path can still be easily specified if it's not found
by CMake by setting the Qt5_DIR cache variable after the initial
configuration run, so this shouldn't present an usability issue.
The main advantage of switching to glad from glLoadGen is that, apart
from being actively maintained, it supports a customizable entrypoint
loader function, which makes it possible to also support OpenGL ES.
Apparently /DEBUG implicitly disables linker optimizations. This
explicitly re-enables them, giving a 40% reduction in binary sizes and
a very slight runtime speed improvement.
Debug was missing compiler flags, causing MSVC to default it to building
with optimizations enabled (making for a not very useful binary for
actual debugging...). Additionally, the variables were re-organized to
remove some redundancy, the old Release build type was removed, and
RelWithDebInfo was renamed to take its place instead.
Remove unneeded stuff from pre-commit script
The check against an empty commit was not needed (it is only a security for the 1st commit after git init).
It could also possibly pose problems because of the redirection to /dev/null on some windows systems.

Passing -pthread to GCC as a flag makes it both link to libpthread, and make C standard library routines reentrant. This makes the additional explicit links unnecessary.
Additionally, on OSX, this is the default behavior, and clang will print a message about it being unused if it's present there.
These are implicitly linked by Xcode, but with this, you can also build it with any other generator, which does not have this behavior.
CoreFoundation is included as a part of Cocoa (which is an umbrella framework), and Cocoa is generally recommended to link against, rather than its individual components (CoreFoundation, Foundation, libobjc, ...).
This both reduces redundancy in add_executable definitions, and makes it easier to link additional libraries. In particular, extra libraries are needed on OSX - see next commit.
This enables the /MP compiler flag, which parallelizes builds of by
distributing compilation of individual object files across workes
processes, instead of being limited to per-project parallelism.
Reduces the time for a full compile from 72 s to 45 s on my machine.
Several cleanups to the buildsystem:
- Do better factoring of common libs between platforms.
- Add support to building on Windows.
- Remove Qt4 support.
- Re-sort file lists and add missing headers.
This should fix the GL loading errors that occur in some drivers due to
the use of deprecated functions by GLEW. Side benefits are more accurate
auto-completion (deprecated function and symbols don't exist) and faster
pointer loading (less entrypoints to load). In addition it removes an
external library depency, simplifying the build system a bit and
eliminating one set of binary libraries for Windows.
After adding FindGLEW.cmake to externals, the variable call for the GLEW include path needed to be revised.
Append flags on OSX, rather than overwrite them.
I realized that GCC_COMPILE_FLAGS was changed to CMAKE_CXX_FLAGS mistakenly, so both were changed to a more platform-independent name.
