# builds Appimage on Centos 7 using linuxdeployqt from continuous build
# expects to work in $WORKSPACE, uses the contents of dist/{bin,share,lib64} copied into an appdir
# missing qt plugins are copied in manually, as are osgPlugins
# libcurl in SIMGEAR needs a setting to find the tls certificate, and OSG needs LD_LIBRARY_PATH so it can find osgPlugins
# currently not including FGDATA, but this could be done easily once FG is updated to change Nav database checks from path to some kind of checksum
# 
# issues/errors:
# can't find qt translations - missing something in my build?
