The xhtml format is always tested, regardless of the default format.
Without this, if the default format is xhtml, CMake gives an error
when trying to add the xhtml test because it was already added.
Now all export tests can be run with:
ctest -R "export"
Only export tests for manuals can be run with:
ctest -R "export/doc"
And only export tests for examples can be run with:
ctest -R "export/examples"
Instead of 'autotests/export/doc/' export tests are prefixed
with 'export/doc/'. This has the advantage of the name better
reflecting the test (export tests are not autotests), but has a
disadvantage in that the old name gave a better idea of where the
export test scripts are located (in the autotests directory).
Many test are not running, but if changed the '-dbg xxx' to '-dbg any'
then all of sudden they pass ...
(The buffered output of lyx is often disrupted too early with 'kill -9',
so the expected data are not available for the appropriate test)
