误删文件夹cmake-build-debugg后，重新运行提示错误：

Error running 'Build': Cannot start process, the working directory '/home/zj/Documents/PICC/c++/cmake-build-debug' does not exist

重新新建cmake-build-debug，再次运行：

====================[ Build | c__ | Debug ]=====================================
/home/zj/software/jetbrains/clion-2018.3.3/bin/cmake/linux/bin/cmake --build /home/zj/Documents/PICC/c++/cmake-build-debug --target c__ -- -j 4

参考：Cmake Error: could not load cache
