SIMD Everywhere finder needs to be installed alongside libobs CMake
package since its headers depends on it.
C++ cmath header is included on Windows on ARM to ensure that all math
functions are correctly defined when included in C++ code.
https://github.com/simd-everywhere/simde/issues/1304
macOS intrinsics is included to make sure that no redefinition error
happens.
Ideally CMAKE_OSX_ARCHITECTURES should not be set automatically within
the project but should exclusively be a cache or environment variable
provided by the developer.
This would also match the requirement mentioned by the CMake
documentation that the value should be set before the first project()
call.
If this variable is not set, the Xcode generator would default to the
native platform of the host, but the buildspec system as well as the
"add_obs_plugin" function need a local "architecture" to work, so
use "CMAKE_HOST_SYSTEM_PROCESSOR" instead if CMAKE_OSX_ARCHITECTURES
was not provided.
CMake doesn't expect CMake package files to be separated in
subdirectories on Windows and instead expects all files to be put in
a single directory `cmake` found within one of the PREFIX paths.
Also fixes circular dependency in w32-pthreads CMake package config
file.
Allows for configuration and build from a read-only-mounted source dir
by setting the build number externally. For example:
`cmake -DOBS_BUILD_NUMBER=1`
Qt Gui virtualkeyboard plugin was removed in Qt 6.x.
Qt Network Bearer Management was removed in Qt 6.0.
Qt Multimedia mediaservice and audio plugins were removed in Qt 6.x.
Currently, when git describe fails to get a git tag for the OBS Version,
a non-fatal message is printed, and the generator is left to continue,
usually ending up with a more cryptic error message down the line.
Instead, print the git output together with a short description of what
actually happened, and exit fatally so the problematic line of code is
clear. An added advantage is that the git output is printed in red
instead of (say) white on color-enabled terminals.
find_qt was necessary during the transitional period between Qt5 and
Qt6. With Qt6 being the only supported Qt version (for open source) for
the time being, code complexity can be reduced for easier maintenance.
Store and read dependency hashes to determine if a dependency needs to
have its extracted copy replaced (e.g., a dependency that had its
revision changed but not its version changed).
qrcodegen is built on obs-deps for macOS and Windows, with the
generated CMake package calling the dependency qrcodegen (not
libqrcoden) and associated target qrcodegen::qrcodegen.
This change updates the finder (required for Linux) to create the same
targets so consumers do not need to differentiate between different
variations of the same dependency on Linux.
Also updates obs-websocket to 5.3.1 to bring in associated CMake
changes.
Compiler extensions are disabled before the first `project` call to
force CMake into considering compilers to not support GNU extensions
(even though clang and gcc do).
Also sets common clang compiler options so they can be used across all
supported platforms.
`openmp-simd` support is enabled by default as there is no performance
penalty on x86_64 systems and intrinsics are enabled on arm64.
Also implements CMake's `CMAKE_COMPILE_WARNING_AS_ERROR` flag to
enable the desired behavior and configuration time.
Include guards ensure that bootstrap includes happen only once for the
entire project. Moving all policy changes into an included file without
its own policy scope ensures that the policy is applied to the project.
OBS CMake build framework 3.0 is a minor overhaul of version 2.0. Due
to close proximity of the 2.0 rework, the amount of actual changes to
project files are minimal and mostly concern application generation.
This commit contains the bootstrap elements only and requires
OS-specific implementations to be functional.
