使用CMAKE查找Direct3d 12

Finding Direct3D 12 using CMake

本文关键字：Direct3d 查找 CMAKE 使用      更新时间：2023-10-16

所以我一直在尝试学习CMAKE并将其与C 一起使用。我想开始创建一种便携式游戏引擎，该引擎在Windows上使用 direct3d 12 。

目前，我的项目有以下CMakeLists.txt：

cmake_minimum_required(VERSION 3.0 FATAL_ERROR)
project(PsychoEngineCore)
set(SRCS_CXX ${CMAKE_CURRENT_LIST_DIR})
include(${CMAKE_CURRENT_SOURCE_DIR}/src/dir_src.cmake)
set(LIB_TYPE "STATIC" CACHE STRING "Static or Dynamic Linking")
if(${CMAKE_CXX_COMPILER_ID} STREQUAL GNU OR
${CMAKE_CXX_COMPILER_ID} STREQUAL Clang)
    set(warnings "-Wall -Wextra -Werror")
elseif(${CMAKE_CXX_COMPILER_ID} STREQUAL MSVC)
    set(warnings "/W4 /WX /EHsc")
endif()
if(NOT CONFIGURED_ONCE)
    set(CMAKE_CXX_FLAGS "${warnings}"
        CACHE STRING "Flags used by the compiler during all build types." FORCE)
endif()
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
# Do we want static libraries?
# When STATIC_LINKING is TRUE, then cmake looks for binaries ending in ".a".
# THIS IS FOR LINUX ONLY!
if(LIB_TYPE EQUAL STATIC)
    if (UNIX AND NOT APPLE)
        set(CMAKE_FIND_LIBRARY_SUFFIXES(".a"))
    endif(UNIX AND NOT APPLE)
    set(CMAKE_EXE_LINKER_FLAGS "-static")
    set_target_properties(surface PROPERTIES LINK_SEARCH_END_STATIC 1)
endif(LIB_TYPE EQUAL STATIC)
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/include)
include(GenerateExportHeader)
add_library(${PROJECT_NAME} ${LIB_TYPE} ${SRCS_CXX})
GENERATE_EXPORT_HEADER(
    ${PROJECT_NAME}
    EXPORT_MACRO_NAME PE_API
    EXPORT_FILE_NAME ${CMAKE_CURRENT_SOURCE_DIR}/include/Engine/API/${PROJECT_NAME}Export.hpp
    DEPRECATED_MACRO_NAME PE_API_DEP
    STATIC_DEFINE PE_STATIC
)

目前，我在以下位置有我的d3d12.lib文件：

C:Program Files (x86)Windows Kits10Libs10.0.16299.0umx64

如果有上述系统可用的较新版本，是否有一种方法可以保持动态的路径动态，最好是"更新"？

谢谢！

将我的评论变成答案

一般来说，只需添加

target_link_libraries((${PROJECT_NAME} d3d12.lib)

Windows SDK(Direct3D SDK现在已成为一部分(在标准搜索路径中，例如图书馆的链接器。因此，它是由MSVC编译器和链接器自动找到的。

我认为，升级到更新的API版本并不是一个好主意。您正在为特定API版本编写程序。

工作示例

这是一个最小的工作示例(测试VS2017 15.5.5，CMAKE 3.9.0(：

cmake_minimum_required(VERSION 3.0)
project(Direct3DExample)
find_package(Git REQUIRED)
set(_path "${CMAKE_BINARY_DIR}/DirectX-Graphics-Samples/Samples/Desktop/D3D12HelloWorld/src/HelloTriangle")
if (NOT EXISTS "${_path}")
    execute_process(
        COMMAND "${GIT_EXECUTABLE}" clone https://github.com/Microsoft/DirectX-Graphics-Samples.git
    )
endif()
file(GLOB _files "${_path}/*")
list(APPEND _shader ${_files})
list(FILTER _files EXCLUDE REGEX "\.vcxproj|\.hlsl")
list(FILTER _shader INCLUDE REGEX "\.hlsl")
get_filename_component(_name "${_path}" NAME)
add_executable(${_name} WIN32 ${_files})
target_compile_definitions(${_name} PRIVATE "UNICODE" "_UNICODE")
target_link_libraries(${_name} PRIVATE "d3d12.lib" "dxgi.lib" "d3dcompiler.lib")
add_custom_command(
    TARGET ${_name}
    POST_BUILD
    COMMAND "${CMAKE_COMMAND}" -E copy ${_shader} $<TARGET_FILE_DIR:${_name}>
)

如果您需要更多(未自动找到Windows SDK的编译器/链接器(，则可能需要查看以下find_package()配置代码：
