From f2eb740f3f0340ad941e563484d5ba45a5ec6af0 Mon Sep 17 00:00:00 2001 From: Charles Giessen Date: Tue, 22 Oct 2024 11:48:46 -0500 Subject: [PATCH] build: Disable Vulkan-Module by default After numerous reports of builds being broken due to the addition of the Vulkan-Module support code in CMake, the option is being set to OFF by default. This prevents projects which do not use the module from not being able to build due to compiler, build system, and platform issues. Projects wishing to enable modules can set the cmake option VULKAN_HEADERS_ENABLE_MODULE=ON to re-enable the module support. Add a warning in case a user decides to enable the module but the platform doesn't support modules. --- CMakeLists.txt | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index a1d49c4..af6cbaf 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -52,9 +52,13 @@ if ((CMAKE_CXX_COMPILER_ID STREQUAL "MSVC" AND (MSVC_VERSION GREATER_EQUAL "1941 set(COMPILER_SUPPORTS_CXX_MODULES TRUE) endif() -option(VULKAN_HEADERS_ENABLE_MODULE "Enables building of the Vulkan C++ module.
