安装
使用源码安装CMake可以对版本进行指定。
首先从Installing | CMake下载对应平台的源码，并进行解压。解压后执行如下命令：
1
2
3
| ./bootstrap
make
sudo make install
|
上述第三条指令为可选指令，仅当拥有超级权限且准备为所有用户安装新版本的CMake时推荐使用，负责使用如下命令在CMake添加到PATH即可。
1
| export PATH=/home/sukie/cmake-3.20.2/bin:$PATH
|
常用命令
编译选项
1
2
| cmake -DCMAKE_INSTALL_PREFIX=../install ..
cmake --install .. --prefix ../install
|
Interface Changing
CMake 3.12中将add_definitions修改为``add_compile_definitions()` 。
1
2
| add_definitions(-DQURL_NO_CAST_FROM_STRING)
add_compile_definitions(QURL_NO_CAST_FROM_STRING)
|
