Generated post build action batch scripts retained an empty token to
the copy command with the used generator expression (as PDBs are only
generated for Debug and RelWithDebInfo configurations).
Moving their copy step into its own command (and using the `true`
CMake command, which is a no-op) ensures that builds in Release and
MinSizeRel correctly finish this step.
Creation of Info.plist files through Xcode is more canonical and
future-proof, as it will automatically pick up changes/updates
introduced by Apple. Non-standard keys can still be added via a
template file, which will then be extended by Xcode with the default
keys.
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.
Also restores original order of compiler flags and more explicitly
splits up flags for the specific languages in which they take effect.
Notice that ObjC and ObjC++ follow a slightly stricter set of rules
than C and C++, which is reflected by this fix.
Frameworks should be archived and exported (where they will be
codesigned by Xcode) or shipped within an App bundle where Xcode will
also take care of it.
Updates the syphon to use the Syphon.framework from obs-deps instead of
the submodule.
The submodule however was not updated in 9 years and additionally had
custom patches, compared to the obs-deps release that's built on the
current git commit of Syphon, meaning that some code changes are
necessary. It would be nice to split the code and cmake changes into
multiple commits (where the first would update the submodule and contain
the plugin code changes, and the second switch the cmake away from the
submodule to the obs-deps release), but it really doesn't make sense to
update the submodule first if it gets removed anyways.
Adds a subclass for SyphonClientBase that is responsible for receiving
the frames. This has the advantage that it doesn't need an OpenGL
context like the existing SyphonOpenGLClient, and can just return an
IOSurface directly (without some kind of middleman).
Camera Extensions require specific entitlements for the hosting app,
which also require a provisioning profile. To avoid breaking local
builds that do not require the camera extension, an additional
entitlements file that will not trigger the provisioning profile
requirement will be used if the virtualcam (but not the Camera
Extension) is configured.
VERSION comparison requires semver-compliant version strings, but
obs-deps versions are based on dates, which are not compliant. Fix
version strings to semver variants before comparison.
As there will be multiple directories containing obs-deps (non-Qt and
Qt variants), the search needs to continue after a first failed attempt
and not abort it entirely.
- Sets CMAKE_C_STANDARD to 17
- Disables C extensions (e.g. gnu17) to force ISO C on macOS/Windows
- Fixes language properties in cmake 3.0 not being set correctly
- Sets Xcode attributes to c17
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.
