Question

每当我构建程序时，我都会调整 Sascha Willems 的 Vulkan Samples 来编译着色器。我知道这个问题已经被问了很多，但我找到的解决方案都不适合我。

这是我的代码：

cmake_minimum_required(VERSION 3.19)
project(Test)

set( ${CMAKE_CURRENT_SOURCE_DIR}/shaders)

set(SHADER_DIR ${CMAKE_CURRENT_SOURCE_DIR}/shaders)
file(GLOB SHADERS ${SHADER_DIR}/*.vert ${SHADER_DIR}/*.frag ${SHADER_DIR}/*.comp ${SHADER_DIR}/*.geom ${SHADER_DIR}/*.tesc ${SHADER_DIR}/*.tese ${SHADER_DIR}/*.mesh ${SHADER_DIR}/*.task ${SHADER_DIR}/*.rgen ${SHADER_DIR}/*.rchit ${SHADER_DIR}/*.rmiss)

file(GLOB SPV_SHADERS ${SHADER_DIR}/*.spv)

find_package(Vulkan)

foreach(SHADER IN LISTS SHADERS)
    get_filename_component(FILENAME ${SHADER} NAME)
    add_custom_command(OUTPUT ${SHADER_DIR}/shaders/${FILENAME}.spv
        COMMAND ${Vulkan_GLSLC_EXECUTABLE} ${SHADER} -o ${SHADER_DIR}/shaders/${FILENAME}.spv
        DEPENDS ${SHADER}
        COMMENT "Compiling ${FILENAME}")
endForeach()

add_custom_target(shaders ALL DEPENDS ${SPV_SHADERS})

add_executable(Test main.cpp ${SHADERS})
add_dependencies(Test shaders)

[编辑]：CMake 似乎跳过了 foreach 循环，我是否正确使用它？

[Edit2]：现在循环有效，但着色器仍未编译

搜索了一下，我删除了 file(GLOB SPV_SHADERS ${SHADER_DIR}/*.spv) 并替换为 list(APPEND SPV_SHADERS ${ASSETS_DIR}/shaders/${FILENAME}.spv)

它看起来像这样：

cmake_minimum_required(VERSION 3.19)
project(Test)

set( ${CMAKE_CURRENT_SOURCE_DIR}/shaders)

set(SHADER_DIR ${CMAKE_CURRENT_SOURCE_DIR}/shaders)
file(GLOB SHADERS ${SHADER_DIR}/*.vert ${SHADER_DIR}/*.frag ${SHADER_DIR}/*.comp ${SHADER_DIR}/*.geom ${SHADER_DIR}/*.tesc ${SHADER_DIR}/*.tese ${SHADER_DIR}/*.mesh ${SHADER_DIR}/*.task ${SHADER_DIR}/*.rgen ${SHADER_DIR}/*.rchit ${SHADER_DIR}/*.rmiss)

find_package(Vulkan)

foreach(SHADER IN LISTS SHADERS)
    get_filename_component(FILENAME ${SHADER} NAME)
    add_custom_command(OUTPUT ${SHADER_DIR}/shaders/${FILENAME}.spv
        COMMAND ${Vulkan_GLSLC_EXECUTABLE} ${SHADER} -o ${SHADER_DIR}/shaders/${FILENAME}.spv
        DEPENDS ${SHADER}
        COMMENT "Compiling ${FILENAME}")
list(APPENDS SPV_SHADERS ${SHADER_DIR}/shaders/${FILENAME}.spv)
endForeach()

add_custom_target(shaders ALL DEPENDS ${SPV_SHADERS})

add_executable(Test main.cpp ${SHADERS})
add_dependencies(Test shaders)

CMake 编译 glsl 着色器
