* Update build to allow setting external mimalloc path (#8676)Lujin Wang2025-10-11
| | | | Update the build to allow setting user-specific path for the external module mimalloc.
* Fix SPIRV headers precedence (#8481)Jay Kwak2025-09-19
| | | | | | | | | | Remove SYSTEM flag from SPIRV-Headers to fix MacOS header precedence. When the path is registered as SYSTEM, it is used with `-isystem` option not `-I` option and it gets less searching order on MacOS. When spirv.h is installed on the system directory, it will end up using the system installed spirv.h, which is most likely an older version than we should use.
* Set default mimalloc for spirv-tools but allow user to override (#8460)Gangzheng Tong2025-09-17
| | | | | | | | | | | | | | | | | | | | | | | | This PR resolves a configuration conflict where the SLANG_ENABLE_SPIRV_TOOLS_MIMALLOC option was defined twice with different defaults, causing user settings to be overridden. Changes: - Removed duplicate definition in external/CMakeLists.txt that only applied to WIN32 - Define default in main CMakeLists.txt - ON by default for Windows - OFF by default for other platforms (still need to resolve crashes so set it to `OFF` for now) Preserved user configuration - explicit -DSLANG_ENABLE_SPIRV_TOOLS_MIMALLOC=value settings are now properly respected Related to https://github.com/shader-slang/slang/issues/8158 --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
* Enable static mimalloc in Spriv-Tools (#8419)Gangzheng Tong2025-09-16
| | | | | | | | | | | | | | | | | | | | | | * Added optional mimalloc integration for SPIRV-Tools to improve compilation performance * Cloning `mimalloc` repo to external/ on demand during cmake config * Enabled by default on Windows, configurable via `SLANG_ENABLE_SPIRV_TOOLS_MIMALLOC` CMake option, to enable static mimalloc build in spirv-tools. * There are some crashes in Linux and Mac with static mimalloc enabled, likely due to the system malloc and mimalloc mixed usage. This might be expected as mimalloc in spirv-tools is not extensively tested according to https://github.com/KhronosGroup/SPIRV-Tools?tab=readme-ov-file#dependency-on-mimalloc. So by default only Windows has this enabled.

* Add more system dependency options to CMake (#7987)Niklas Korz2025-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | Allows opt-in for sourcing the following dependencies from the system, instead of using the vendored ones: - miniz - lz4 - vulkan-headers - spirv-tools - glslang (some of these already had options that weren't working, as either it expected them to be static libraries or it was expecting to be embedded in another CMakeList that should provide the package, instead of finding the package itself) This is based on a patch we currently maintain inside nixpkgs, but as it frequently conflicts with new slang releases, it would be nice to see get this upstream. --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Sam Estep <sam@samestep.com>
* CMake: Guard inclusion of VULKAN_HEADERS and SPIRV-Headers (#8124)Sergei Popov2025-08-19
| | | | | | | | | | | Don't include the VULKAN_HEADERS and SPIRV-Headers submodule if they are already included.

* Fix SLANG_USE_SYSTEM_SPIRV_HEADERS=TRUE (#7916)Ellie Hermaszewska2025-07-25
| | | | | | find_package is locally scoped, so like other find_packages we should do it at the top level Closes https://github.com/shader-slang/slang/issues/7643
* Fix SLANG_USE_SYSTEM_SPIRV_HEADERS (#7371)Emil Imbert Villumsen2025-06-13
| | | | | | | | | | | | | | | | | | * Use aliased SPIRV-Headers::SPIRV-Headers to also work with an installed SPIRV-Headers SPIRV-Headers standalone is only defined when using sources directly. When consuming an installed SPIRV-Headers via find_package, the full SPIRV-Headers::SPIRV-Headers must be used. The full syntax is supported by both source and installed builds. * Fix SLANG_USE_SYSTEM_SPIRV_HEADERS - Use find_package to bring in SPIRV-Headers cmake targets - Set SPIRV-Headers_SOURCE_DIR as a workaround when including spirv-tools - Query cmake for SLANG_SPIRV_HEADERS_INCLUDE_DIR location, supporting default, SLANG_OVERRIDE_SPIRV_HEADERS_PATH and find_package builds. - Cleanup unnecessary SPIRV_HEADER_DIR (unconditionally overwritten in spirv-tools)
