CMake 編譯 glsl 着色器

Question

每當我構建程序時，我都會調整 Sascha Willems 的Vulkan Samples來編譯着色器。 我知道這個問題已經被問了很多，但我發現沒有一個解決方案對我有用。

這是我的代碼：

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)

[編輯]：CMake 似乎跳過了 foreach 循環我是否正確使用它？

[Edit2]：現在循環工作，但着色器仍未編譯

Answer 1

經過一番搜索，我刪除了file(GLOB SPV_SHADERS ${SHADER_DIR}/*.spv)並將其替換為list(APPEND SPV_SHADERS ${ASSETS_DIR}/shaders/${FILENAME}.spv)

它看起來像這樣：

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)
