clion Of toolcchain To correspond ,msvc yes default.nmake.exe, cl.exe

Process finished with exit code -1073741515 (0xC0000135) Do you have any questions 139

The background of this problem is build normal , But the runtime will report this error . This is because clion Can't find qt Of dll Dynamic library .
Same question
Add environment variables and method 2 to method 1 in this post , Copy dll Can solve problems .（ The essential reason is that the dynamic library needs to be found by the code , So you need to add it to the environment variable . Or put it in the running directory of the program ）
Be careful ： To match the code selected toolchain Corresponding , The choice is msvc The added directory is {QtVersion}\msvc2017_64\bin
