failing to build on linux (ubuntu & xubuntu 18.04): cp: cannot stat 'libpng15.bc': No such file or directory

Hi! We killed about two weekends in trying to build UE 4.24 with HTML5 support %) We try Ubuntu and Xubuntu 18.04, try two locales - ru & en - and got the same crash. Help us plz))

Here what we got as output when run HTML5Setup.sh: ` :~/UE4HTML5/ue4-r424-html5/Engine/Platforms/HTML5$ ./HTML5Setup.sh Writing .emscripten configuration file to user home directory /home/bl/UE4HTML5/ue4-r424-html5/Engine/Platforms/HTML5/Intermediate/ Backing up old Emscripten configuration file in /home/bl/UE4HTML5/ue4-r424-html5/Engine/Platforms/HTML5/Intermediate/.emscripten.old The Emscripten configuration file /home/bl/UE4HTML5/ue4-r424-html5/Engine/Platforms/HTML5/Intermediate/.emscripten has been rewritten with the following contents:
