Question

我的源代码目录结构如下：

.
├── build
├── CMakeLists.txt
├── libs
│   ├── CMakeLists.txt
│   ├── ext
│   │   └── include
│   │       └── json.hpp
│   └── int
│       ├── CMakeLists.txt
│       └── net
│           ├── CMakeFiles
│           │   ├── CMakeDirectoryInformation.cmake
│           │   └── progress.marks
│           ├── cmake_install.cmake
│           ├── CMakeLists.txt
│           ├── include
│           │   ├── connection.hpp
│           │   └── conn_manager.hpp
│           ├── Makefile
│           └── src
│               ├── CMakeFiles
│               │   ├── CMakeDirectoryInformation.cmake
│               │   ├── libs.dir
│               │   │   ├── build.make
│               │   │   ├── cmake_clean.cmake

│               │   │   ├── link.txt
│               │   │   └── progress.make
│               │   └── progress.marks
│               ├── cmake_install.cmake
│               ├── CMakeLists.txt
│               ├── connection.cpp
│               ├── conn_manager.cpp
│               └── Makefile
└── main
    ├── CMakeLists.txt
    ├── config
    │   └── config.json
    └── srcs

        └── samvaadak.hpp

＆＃34;建立＆＃34;是我运行cmake的文件夹。它运行并在build / dist / bin中创建最终输出可执行文件。但它也会在源代码树（libs和main）中创建大量中间内容并使其变得杂乱无章。

顶级CMakeLists.txt文件如下所示。

project (samvaadak)
subdirs(main libs)
set (CMAKE_CXX_STANDARD 11)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dist/lib)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dist/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dist/bin)

中级CMakeLists.txt文件包含以下内容：

subdirs(src)

并且，源文件所在的内部文件夹的CMakeLists.txt文件是这样的：

include_directories(${samvaadak_SOURCE_DIR}/libs/int/net/include)
include_directories(${samvaadak_SOURCE_DIR}/libs/ext/include)
add_library(nettu conn_manager.cpp connection.cpp)

set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dist/lib)
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dist/lib)
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/dist/bin)

如何告诉cmake在 libs 和主要文件夹之外构建并在构建内部构建所有内容？

Answer 1

您可以在源代码构建中禁用：

set(CMAKE_DISABLE_IN_SOURCE_BUILD ON)

还建议：

set(CMAKE_DISABLE_SOURCE_CHANGES ON)

需要在第一个project()命令之前使用它们。

cmake out of source build不适用于嵌套源目录
