Do not bundle translations with a binary,
package them to system dir and use %lang tagging in package.

some paths debug:
  qWarning() << "language: " << language;
  qWarning() << "qtpath: " << QLibraryInfo::location(QLibraryInfo::TranslationsPath);
  qWarning() << "apppath: " << a.applicationDirPath();
  qWarning() << "curdir: " << QDir::currentPath();

TODO: add install target
TODO: make it configurable via cmake params.
