The qtdir setting took on much less importance with Qt 5. We've never
officially supported building Qt 5 with kdesrc-build, and qmake and
cmake both use qmake or similar Qt-provided config information to find
Qt, rather than using the unsupported QTDIR environment variable.
As a result, default the value to an empty string (interpreted as use of
system Qt) and stop adding it automatically to the environment variables
defined during the build. If set, it will continue to be used for now.
This also helps the environment setup driver detect when it should look
for the system Qt5 qmake.
The docs have been at docs.kde.org for a long time, now they're the one
and only recommended location. But I forgot to update the URLs
referenced by the script itself. :(
BUG:357162
FIXED-IN:16.01
Right now kdesrc-build will default to kdesrc-buildrc-sample if no
configuration file is present, but that won't be appropriate now that
KF5 is out. Make the user make a choice instead.
The various READMEs and help texts would probably need to be updated to
match, if anyone wants to help. ;)
