Linux下的CMake是一个跨平台的构建工具,它可以自动生成与编译系统无关的Makefile文件,用来编译、链接和打包软件项目。CMake可以简化项目的构建过程,使得开发者更加方便地进行跨平台开发。引用中提到了在Ubuntu 18.04中安装CMake的方法,可以使用命令sudo apt install cmake进行安装。安装完成后,使用cmake -version命令可以查看CMake的版本号。引用中给出了一个简单的样例,通过输入cmake .. && make命令可以编译出main1,如果想编译出main2,则需要将MYDEBUG设置为ON,再次运行cmake .. && make命令进行重新编译。引用中给出了一个CMakeLists.txt文件的示例,其中定义了工程的信息和要生成的elf文件名字及源文件的路径。使用cmake命令运行CMakeLists.txt文件,会根据文件中的配置生成Makefile和其他一些自动生成的文件。然后使用make命令进行编译,最终会生成所需的elf文件。

CMake是一个跨平台的开源构建工具,用于管理和构建软件项目。它使用简单的配置文件(CMakeLists.txt)来描述项目的构建过程,并生成适用于不同平台和编译器的构建脚本。以下是关于Linux下使用CMake的一些注意事项和常用指令:
1. 注意事项:
- CMake构建专用定义文件,文件名严格区分大小写。
- 项目存在多个目录时,可以每个目录都放一个CMakeLists.txt文件,也可以只用一个CMakeLists.txt文件管理。
- 名称中只能使用字母、数字、下划线和破折号。
- 使用`${}`来引用变量。
- 参数之间使用空格进行间隔。
2. 常用指令:
- `add_executable(target_name source_files)`:添加可执行文件。
- `add_library(target_name source_files)`:添加静态或动态库。
- `target_link_libraries(target_name library_name)`:链接库到目标文件。
- `include_directories(directory_path)`:添加头文件搜索路径。
- `link_directories(directory_path)`:添加库文件搜索路径。
- `set(variable_name value)`:设置变量的值。
- `if(condition)`和`endif()`:条件判断语句。
- `foreach(variable IN items)`和`endforeach()`:循环语句。
这是一个简单的示例,展示了如何使用CMake构建一个简单的C++项目:
```cmake
cmake_minimum_required(VERSION 3.0)
project(MyProject)
# 添加可执行文件
add_executable(myapp main.cpp)
# 添加头文件搜索路径
include_directories(include)
# 链接库到目标文件
target_link_libraries(myapp mylib)
# 设置变量的值
set(SRC_FILES src/file1.cpp src/file2.cpp)
# 循环语句
foreach(file ${SRC_FILES})
message("Source file: ${file}")
endforeach()
```

CMake is a cross-platform open-source build system that is widely used for building software projects. It provides a simple and efficient way to define, configure, and generate build files for various platforms and build environments.
To use CMake in Linux, you can follow these steps:
1. Install CMake: You can install CMake from the official website or using your package manager. For example, in Ubuntu, you can use the following command to install it:
```
sudo apt-get install cmake
```
2. Create a CMakeLists.txt file: Create a text file named "CMakeLists.txt" in the root directory of your project. This file will contain the instructions for building your project.
3. Configure the project: Open a terminal and navigate to your project's root directory. Run the following command to configure your project using CMake:
```
cmake .
```
This command will generate the necessary build files based on the instructions provided in the CMakeLists.txt file.
4. Build the project: After configuring the project, you can build it using the following command:
```
make
```
This command will compile the source code and generate the executable or library files specified in the CMakeLists.txt file.
5. Run the project: Once the build process is complete, you can run your project by executing the generated executable file.
These are the basic steps to use CMake in Linux. You can customize the CMakeLists.txt file according to your project's requirements, including specifying source files, libraries, compiler options, etc.
