Copy all the necessary libs to build/bin folder during building app

[pktiuk]

It would make development on Windows easier, because currently launching app after building on windows results in error caused by missing libs. Aftec copying them into bin directory (next to executable) everything works fine.
Full fist of libs, which should be placed there:

libcrypto-1_1-x64.dll
libEGLd.dll
libgcc_s_seh-1.dll
libGLESv2d.dll
libssl-1_1-x64.dll
libstdc++-6.dll
libwinpthread-1.dll
Qt5Concurrentd.dll
Qt5Cored.dll
Qt5Guid.dll
Qt5Networkd.dll
Qt5Widgetsd.dll
SDL2.dll
