How to start Nextcloud Desktop?

I’m currently working on the Desktop version of Nextcloud to make a personal version (change of logo, texts in reference to Nextcloud,…) and I have several questions:

  • I managed to compile the Desktop project without problems or errors, in a folder “nextcloud-desktop-client”. I’ve an executable file in the bin/ directory, but I can’t launch it. Is it possible to run it on debian, or should I try on an Opensuse/Windows version?
  • what exactly do the commands mentioned on the README of the nextcloud repository do?
    $ cmake . -DCMAKE_INSTALL_PREFIX=~/nextcloud-desktop-client -DCMAKE_BUILD_TYPE=Debug ``make install
  • On which OS is it easier to compile Nextcloud Desktop to modify the code and make a custom version?

Thanks in advance for your help and have a nice day,
