如何在使用 Cmake 构建期间编译 HLSL 着色器？

Question

我正在开发一个 d3d 应用程序，我想在使用 cmake 构建期间编译我的 .hlsl 着色器。我不知道从哪里开始。

这是我现在的CMakeLists.txt

cmake_minimum_required(VERSION 3.20)
project(Direct3DTut)

set(CMAKE_CXX_STANDARD 17)

add_executable(${PROJECT_NAME} WIN32
                WinMain.cpp Window.cpp MessageHandler.cpp Graphics.cpp
                Keyboard.cpp Mouse.cpp
                Utils.cpp)

set(LIBS d3d11 D3DCompiler)
target_link_libraries(${PROJECT_NAME} ${LIBS})

我将此模式用于可与 Ninja 和 MSVC 生成器一起使用的 CMake 着色器。

# Build HLSL shaders
add_custom_target(shaders)

set(HLSL_SHADER_FILES VertexShader.hlsl PixelShader.hlsl)

set_source_files_properties(VertexShader.hlsl PROPERTIES ShaderType "vs")
set_source_files_properties(PixelShader.hlsl PROPERTIES ShaderType "ps")
set_source_files_properties(${HLSL_SHADER_FILES} PROPERTIES ShaderModel "4_0")

foreach(FILE ${HLSL_SHADER_FILES})
  get_filename_component(FILE_WE ${FILE} NAME_WE)
  get_source_file_property(shadertype ${FILE} ShaderType)
  get_source_file_property(shadermodel ${FILE} ShaderModel)
  add_custom_command(TARGET shaders
                     COMMAND fxc.exe /nologo /Emain /T${shadertype}_${shadermodel} $<IF:$<CONFIG:DEBUG>,/Od,/O1> /Zi /Fo ${CMAKE_BINARY_DIR}/${FILE_WE}.cso /Fd ${CMAKE_BINARY_DIR}/${FILE_WE}.pdb ${FILE}
                     MAIN_DEPENDENCY ${FILE}
                     COMMENT "HLSL ${FILE}"
                     WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
                     VERBATIM)
endforeach(FILE)

...

add_dependencies(${PROJECT_NAME} shaders)

I use this in my DirectX Tool Kit tutorials. You can also see the rest of the CMake on directx-vs-templates.
