In the win7 system, an error occurred compiling the mission planner source code, and the two output file paths were the same as shown in the figure below

I need help in win7 64-bit system, the source code of the error code that I appear is not wrong is the setting error of VS2017, I don’t know where to set it.

                                                                                                                   Thank you for your participation![1532315388(1)|690x254](upload://kIIeb8ibp7kkcvhQEfuP5sPduF0.png)
