Go to this build-folder. The runtime program is placed by default in the Debug folder:
Double-click to execute this executable program, the results found does not perform, such as the following dialog box:
The reason is that the program does not find the corresponding library when it executes.
Next. We change the system environment variables by changing them. Let Qt run the program to find the library it depends on.
A) Locate the path of the dependent library:C:\Qt\Qt5.5.0\5.5\mingw492_32\bin and then copy its path.
b) Changing environment variables

Paste the previously copied C:\Qt\Qt5.5.0\5.5\mingw492_32\bin into the path, followed by a semicolon ";" Cutting.
The executable program is then executed again. Suppose the program still cannot execute. Restart your computer and you will be able to.
