如何防止 CMake 在生成项目的根目录添加 CMakeLists.txt？

Question

我有以下CMakeLists.txt ：

cmake_minimum_required(VERSION 3.15.5)

project(REminiscence VERSION 0.4.5)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED True)

configure_file(REminiscenceConfig.h.in REminiscenceConfig.h)

add_definitions(-DUSE_MODPLUG -DUSE_STATIC_SCALER -DUSE_TREMOR -DUSE_ZLIB)

set_property(GLOBAL PROPERTY USE_FOLDERS ON)

set(RE_SRC
    "collision.cpp"
    "cpc_player.cpp"
    "cutscene.cpp"
    "decode_mac.cpp"
    "dynlib.cpp"
    "file.cpp"
    "fs.cpp"
    "game.cpp"
    "graphics.cpp"
    "main.cpp"
    "menu.cpp"
    "mixer.cpp"
    "mod_player.cpp"
    "ogg_player.cpp"
    "piege.cpp"
    "protection.cpp"
    "resource.cpp"
    "resource_aba.cpp"
    "resource_mac.cpp"
    "scaler.cpp"
    "screenshot.cpp"
    "seq_player.cpp"
    "sfx_player.cpp"
    "staticres.cpp"
    "systemstub_sdl.cpp"
    "unpack.cpp"
    "util.cpp"
    "video.cpp"
)

source_group("Sources" FILES ${RE_SRC})

set(RE_INC
    "cpc_player.h"
    "cutscene.h"
    "decode_mac.h"
    "dynlib.h"
    "file.h"
    "fs.h"
    "game.h"
    "graphics.h"
    "intern.h"
    "menu.h"
    "mixer.h"
    "mod_player.h"
    "ogg_player.h"
    "resource.h"
    "resource_aba.h"
    "resource_mac.h"
    "scaler.h"
    "screenshot.h"
    "seq_player.h"
    "sfx_player.h"
    "systemstub.h"
    "unpack.h"
    "util.h"
    "video.h"
)

source_group("Headers" FILES ${RE_INC})

add_executable(REminiscence ${RE_SRC} ${RE_INC})

find_package(SDL2 CONFIG REQUIRED)
target_link_libraries(REminiscence PRIVATE SDL2::SDL2 SDL2::SDL2main)

find_package(ZLIB REQUIRED)
target_link_libraries(REminiscence PRIVATE ZLIB::ZLIB)

target_include_directories(REminiscence PUBLIC
    "${PROJECT_BINARY_DIR}"
)

当我生成 Visual Studio 解决方案时，它还将CMakeLists.txt放在根目录下：

问题

如果可能，如何防止 CMake 在根目录添加CMakeLists.txt ？

Answer 1

您不能从项目中删除CMakeLists.txt ，这是设计使然。

cmake将CMakeLists.txt作为依赖项添加到项目中。 如果即使在外部编辑器中修改它， MSBuild运行cmake. 更新项目。 您不需要运行cmake. 和cmake --build手动构建，当您 select构建解决方案时，Visual Studio 会为您完成。

此外，如果CMakeLists.txt在项目中，您可以直接在 Visual Studio 中轻松编辑它。

Answer 2

旁注：如果您希望 CMakeLists.txt 条目出现在项目根目录之外的另一个“文件夹”中，只需将"CMakeLists.txt"条目添加到相应的source_group变量。 CMakeLists.txt 仍将是一个依赖项，但将在 Visual Studio 中的所选文件夹下列出。
