I got the same problem on a different project today.
No cdash subprojects, 2 or 3 ExternalProjects and the big main project.
When CTEST_USE_LAUNCHERS is TRUE, the build fails, but the dashboard is green,
0 build errors, 0 warnings.
The build fails in the main project, not in the ExternalProjects.
This is with cmake 2.8.9.
Strange is that it works without problems for a similar project, which also
has a few ExternalProjects, and where I didn't find differences in the setup
or anything yet.
Any tips how to debug what is going wrong ?
I will look further into it next week.
