Maximilian Bosch 37032db583 chessx: fix build (#46359) ... See https://hydra.nixos.org/build/80998335. Upstream doesn't support QT 5.11 ATM which broke compilation: ``` src/dialogs/savedialog.cpp: In constructor ‘SaveDialog::SaveDialog(QWidget*, Qt::WindowFlags)’: src/dialogs/savedialog.cpp:37:34: error: invalid use of incomplete type ‘class QButtonGroup’ group = new QButtonGroup(this); ``` The Arch community recommends to use an older QT version to fix this (https://aur.archlinux.org/packages/chessx/). Furthermore the `QT_PLUGIN_PATH` wasn't set properly which broke the runtime since QT coudln't find the `xcb` plugin: ``` qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in "" This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. ``` Finally, some minor style fixes were made for consistent indentation. Addresses #45960		2018-09-08 14:19:24 +02:00
