clion 通用 Cmake

clion setting

1.setting -> build -> cmake -> cmake options
	-DCMAKE_TOOLCHAIN_FILE=./build/arch/arm-linux-cross-compile.cmake
	-DCMAKE_INSTALL_PREFIX=/home/xxx/app
	-DCMAKE_EXPORT_COMPILE_COMMANDS=ON   会在 build\target 目录下生成 compile-command.json，包含各个文件编译命令，用于 debug


2.setting -> build -> cmake -> build directory
	build\target

3.Cache variables
	cmake 加载之后可以查看

4. 添加 TODO
	// TODO 方便快速定位找到的位置

5. 映射，自动上传
	- 映射
		setting -> build -> Deployment
			1. + 新建映射环境，mappings -> Deployment path
			2. 右键 环境 -> use as default
			3. excluded paths 排除映射的文件
	- 自动上传
		deployment -> options
			- upload file to default server =>  never -> always
				delete remote file when local are deleted
			- create empty directories
			- delte target items when ones


6. 从 git 新建项目
	file -> new -> project from version control
		填 git 路径即可

7. Clion 使用环境变量
	修改 /etc/environment, 添加 PATH=$PATH:/xxx 即可

8. toolchain
	setting -> build -> toolchain
	1. setting 符号 -> 添加 ssh 环境
	2. + -> 添加 toolchain

9. 选择工具链
	2.setting -> build -> cmake -> toolchain
		选择刚刚建的即可
