ifw package creation failed if window icon and logo have same name
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.
