How to use exe files after building the project?

[uLtRaLoVeR]

I'm using QtCreator with C++
I have developed a small application for test and learning purposes. When I tried to build and run from QtCreator nothing is problem.
However, when I want to run exe file in the release folder of the project. It gives an error.

libstdc++-6.dll not found.

How can I run this exe?

For now, just put all the dlls required into the release folder for checking. Else you go with wysota. Build statically.
