There needs to be a file called 'grain.xml' below this URL. It needs to have the XML format of a KLayout package definition file.
This URL will be used for the package file: https%3A%2F%2Fgithub.com%2Fgdsfactory%2Fglobalfoundries-pdk-libs-gf180mcu_fd_pr.git%2Fbranches%2Fklayout2%2Fklayout/grain.xml.
