对cmake的理解

对cmake的理解：

　　cmake官方文档：https://cmake.org/documentation/

 

　　我们这里只介绍一下对cmake命令行的理解：

Generate a Project Buildsystem
 cmake [<options>] <path-to-source>
 cmake [<options>] <path-to-existing-build>
 cmake [<options>] -S <path-to-source> -B <path-to-build>

Build a Project
 cmake --build <dir> [<options>] [-- <build-tool-options>]

Install a Project
 cmake --install <dir> [<options>]

Open a Project
 cmake --open <dir>

Run a Script
 cmake [{-D <var>=<value>}...] -P <cmake-script-file>

Run a Command-Line Tool
 cmake -E <command> [<options>]

Run the Find-Package Tool
 cmake --find-package [<options>]

View Help
 cmake --help[-<topic>]

　　作者在编译中主要用到了第一条命令cmake [<options>] <path-to-source>

　　在build tree目录下编译source tree，source tree里面必须有cmake要解析的CMakeLists.txt
