SubProjects not reporting from single run

[cmcknigh]

Bug report

When configuring a large multi-project cmake system.
Trying to implement a project setup so I can call 1 ctest command, and all sub projects will report as subprojects to one build in the dashboard.
This may be an issue with missing details in the cmake files, or an issue with ctest not creating/including the details cdash needs to display this data. I have tried just about everything I can find online for how this should be structured.

Results:

When I run ctest -V -S CTestRun.cmake from the sub projects directly the subproject is reported as expected,
But when running ctest from the root of the project...

Expected Behavior

...I would expect that all of the subprojects report with related subproject displayed on the dashboard

Actual Behavior

...I do not see subprojects when I run from the root, only when I run the subproject individually

CDash Version

tried with v3.1.0 and v4.2.0
