根目录下的CMakeLists.txt文件内容如下:

bash 复制代码

cmake_minimum_required(VERSION 3.10)
project(MyProject VERSION 1.0.0)

# 设置C标准
set(CMAKE_C_STANDARD 11)
set(CMAKE_C_STANDARD_REQUIRED ON)

# 设置安装前缀（out目录）
set(CMAKE_INSTALL_PREFIX ${CMAKE_SOURCE_DIR}/out)
message(STATUS "Install prefix: ${CMAKE_INSTALL_PREFIX}")  # 调试信息

# 添加子目录
add_subdirectory(app)
add_subdirectory(tools)

app目录下的CMakeLists.txt文件内容如下：

bash 复制代码

set(APP_TARGET "app")

set(APP_SRC main.c)

add_executable(${APP_TARGET} ${APP_SRC})

install(TARGETS ${APP_TARGET}
        RUNTIME DESTINATION bin)

tools目录下的CMakeLists.txt文件内容如下:

bash 复制代码

add_subdirectory(test)

tools/test目录下的CMakeLists.txt文件内容如下:

bash 复制代码

set(TEST_TARGET "test")
set(TEST_SRC main.c)

add_executable(${TEST_TARGET} ${TEST_SRC})

# 关键：必须添加 install 命令
install(TARGETS ${TEST_TARGET}
        RUNTIME DESTINATION bin
)
