Thank you Brad,
I am looking into it.

I haven't figured it all out yet but it looks like CTest is currently 
waiting for dependencies to finish which have never (and will never) run 
because their executable is missing.
It does not happen when the dependency has a regular test failure

I've come up with this testcase which I'll include with the fix (as soon 
as I have one) which reproduces this:
     cmake_minimum_required(VERSION 2.8.12)

     enable_testing()

     add_test(test1 ${CMAKE_COMMAND} -E echo test)
     add_test(test2 non-existent-command)
     set_tests_properties(test1 PROPERTIES DEPENDS test2)
