CMake的一些正确姿势

0，设置Debug / Release:

CMakeLists.txt:

SET(CMAKE_BUILD_TYPE "Debug”)
or
SET(CMAKE_BUILD_TYPE "Release")

用参数设置

mkdir Release  
cd Release  
cmake -DCMAKE_BUILD_TYPE=Release ..  
make  

mkdir Debug  
cd Debug  
cmake -DCMAKE_BUILD_TYPE=Debug ..  
make  

1，output data file position

上面的一定是Naja Makefile.竟然不是NMake......

所以要在别的编辑器上例如Qt IDE:

 QT Ide认 编译器 的方法是在一个Bat文件，这个bat会设置环境变量，应该是从这里面解析的:

CLION就比较智能：
