Makefile 为什么CMake要删除添加\自定义\命令的源文件

我有一个CMake函数，它将一些（GLSL）代码编译成运行源代码所需的格式。该函数获取一些输入文件，在这些文件上运行一些脚本，并输出一些相应的文件。该函数在Windows上运行良好，并生成我的输出。但是，在Mac（Unix？）上，我的源（输入）在生成输出后被删除。为什么会这样

以下是我的功能：

# adds a custom target that compiles the GLSL code using the compile-glsl-code.py python script
function(build_glsl)
    set(optionArgs "")
    set(oneValueArgs "TARGET" "VULKAN")
    set(multiValueArgs "SOURCES")
    cmake_parse_arguments(FUNCTION_ARGS "${optionArgs}" "${oneValueArgs}" "${multiValueArgs}" ${ARGN})

    # Make sure python is installed
    find_package(Python3 COMPONENTS Interpreter)
    if (NOT Python3_FOUND)
        message(FATAL_ERROR "Could not find python3!")
    endif()

    if(WIN32)
        set(glslangValidator ${FUNCTION_ARGS_VULKAN}/Bin/glslangValidator.exe)
    else()
        set(glslangValidator ${FUNCTION_ARGS_VULKAN}/bin/glslangValidator)
    endif()
    set(spvConverter ${CMAKE_SOURCE_DIR}/src/spv-converter.py)
    set(entryPoint "main")
    set(GLSL_COMPILED_SOURCES "")
    foreach(file IN LISTS FUNCTION_ARGS_SOURCES)
        if(file MATCHES ".*.vert.glsl$" OR file MATCHES ".*.frag.glsl$" OR file MATCHES ".*.geom.glsl$" OR file MATCHES ".*.tesc.glsl$" OR file MATCHES ".*.tese.glsl$" OR file MATCHES ".*.comp.glsl$")
            set(tmpFile ${file}.tmp.spv)
            set(outputFile ${file}.spv)
            list(APPEND GLSL_COMPILED_SOURCES ${outputFile})
            add_custom_command(
                OUTPUT ${outputFile}
                COMMAND ${glslangValidator} "-V" "--entry-point" "${entryPoint}" "${file}" "-o" "${tmpFile}" # compile ${file} into ${tmpFile}
                COMMAND ${Python3_EXECUTABLE} ${spvConverter} "${tmpFile}" "${outputFile}" # compile ${tmpFile} into ${outputFile}
                COMMAND ${CMAKE_COMMAND} -E remove -f ${tmpFile} # delete ${tmpFile}
                SOURCES ${file}
                VERBATIM
            )
        endif()
    endforeach()

    add_custom_target(${FUNCTION_ARGS_TARGET}
        SOURCES ${FUNCTION_ARGS_SOURCES}
        DEPENDS ${GLSL_COMPILED_SOURCES}
        VERBATIM
    )
endfunction()

简而言之，这一部分：

add_custom_command(
    OUTPUT ${outputFile}
    COMMAND ${glslangValidator} "-V" "--entry-point" "${entryPoint}" "${file}" "-o" "${tmpFile}" # compile ${file} into ${tmpFile}
    COMMAND ${Python3_EXECUTABLE} ${spvConverter} "${tmpFile}" "${outputFile}" # compile ${tmpFile} into ${outputFile}
    COMMAND ${CMAKE_COMMAND} -E remove -f ${tmpFile} # delete ${tmpFile}
    SOURCES ${file}
    VERBATIM
)

glslangValidator和python脚本不会删除源文件。如果我删除

命令${CMAKE_COMMAND}-E remove-f${tmpFile}

行，那么它不会删除我的源代码（也不会删除tmp文件），但我确实想删除tmp文件。是什么原因导致了这种情况？

添加自定义命令

不知道

来源

关键字。对于命令所依赖的指定文件，请使用

depends

关键字。（在您当前的代码中，

SOURCES

和

${file}

都成为上一个命令的一部分，这就是它删除源文件的原因。您可以使用

make VERBOSE=1

检查在构建过程中执行的确切命令）。我的伙计。谢谢
