cmake add_custom_command永远不会运行

但是指定的答案无法解决我的问题，也是针对较新版本的Cmake（3.20），

我希望每次阴暗器源更改时都将某些文件（着色器文件）复制到可执行的目录中，

所以我有CMAKE中的以下代码：

add_custom_command(
    OUTPUT ${CMAKE_BINARY_DIR}/Shaders.txt
    COMMAND ${CMAKE_COMMAND} -E echo "Actually Copying shaders"
    COMMAND ${CMAKE_COMMAND} -E copy_directory ${CMAKE_CURRENT_SOURCE_DIR}/assets/ $<TARGET_FILE_DIR:Editor>/assets
    COMMAND ${CMAKE_COMMAND} -E touch ${CMAKE_BINARY_DIR}/Shaders.txt
    DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/assets
)

add_custom_target(CopyShaders ALL DEPENDS ${CMAKE_BINARY_DIR}/Shaders.txt)

据我了解，现在将始终构建CopyShaders（因为它总是过时的），但是Shaders.txt只能构建一次（更改着着色器源后），之后它开始了迄今为止，

我正在尝试使用cmake构建目标检查员 - 构建构建 - 目标copyshaders

如果我使用的是mingw，则“实际上复制着着色器”就永远不会打印，如果存在着色器.txt.txt ，即使我使用的MSVC使用了包含着色器的资产文件夹已修改

，我也会在终端上获取以下警告：

 warning MSB8064: Custom build for item "D:\Acads\Programming\opengl\SummerOfCode\build\CMakeFiles\05fb3856b7a5e1f6ce1ea66ca9091779\Shaders.txt.rule" succeeded, but specified dependency "d:\acads\programming\opengl\summerofcode\editor\assets" does not exist. This may cause incremental build to work incorrectly. [D:\Acads\Programming\opengl\SummerOfCode\build\Editor\CopyShaders.vcxproj]

同样，我确实有存在的文件夹

My question is very similar to cmake: add_custom_command / add_custom_target ignoring dependency

But the answer specified does not solve my issue, and also it is for a newer version of cmake (3.20)

I want some files (shader files) to be copied to the executable directory every time the shader source changes

So I have the following code in cmake:

add_custom_command(
    OUTPUT ${CMAKE_BINARY_DIR}/Shaders.txt
    COMMAND ${CMAKE_COMMAND} -E echo "Actually Copying shaders"
    COMMAND ${CMAKE_COMMAND} -E copy_directory ${CMAKE_CURRENT_SOURCE_DIR}/assets/ lt;TARGET_FILE_DIR:Editor>/assets
    COMMAND ${CMAKE_COMMAND} -E touch ${CMAKE_BINARY_DIR}/Shaders.txt
    DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/assets
)

add_custom_target(CopyShaders ALL DEPENDS ${CMAKE_BINARY_DIR}/Shaders.txt)

Now, as I understand, CopyShaders will always be built (since it is always out of date), but Shaders.txt should only be built once (after the shader source is changed), after which it is up to date

I'm trying to build the target CopyShaders using cmake --build build --target CopyShaders

If I'm using MinGW, then "Actually copying shaders" never gets printed if Shaders.txt is present, even if the assets folder containing the shaders has been modified

If I'm using MSVC, I get the following warning on the terminal:

 warning MSB8064: Custom build for item "D:\Acads\Programming\opengl\SummerOfCode\build\CMakeFiles\05fb3856b7a5e1f6ce1ea66ca9091779\Shaders.txt.rule" succeeded, but specified dependency "d:\acads\programming\opengl\summerofcode\editor\assets" does not exist. This may cause incremental build to work incorrectly. [D:\Acads\Programming\opengl\SummerOfCode\build\Editor\CopyShaders.vcxproj]

Again, I do have the folder existing
