The creation of an IFW package fails if `CPACK_IFW_PACKAGE_WINDOW_ICON` and `CPACK_IFW_PACKAGE_LOGO` point to files with the same name. (Path is not necessarily the same.) ``` Caught exception: Could not copy the Logo file from '/home/user/build/program/_CPack_Packages/Linux/IFW/program-g123123123-Linux/config/icon.png' to '/tmp/binarycreator-LG6pnQ/installer-config/icon_png.png' Error: 'Target already exist.'. ``` Running cmake 3.6.3 and IFW 2.0.3 on linux.
