I use qt + google test to run tests in my build environment.

The problem I have, is in some (most) of my unit test directories, there will 
be multiple test executables created, all dependent on the same output file 
from the add_resources step.

Typically its something like

qt_add_resource( resourceVar resource.qrc )

add_executable( test1 test1main.cpp ${resourceVar} )
add_executable( test2 test2main.cpp ${resourceVar} )

On windows (running the build from cmake through visual studio with parallel 
building turned on) this sometimes (1 out of 20 or 30 builds or so) causes a 
race condition, where the dependency on the qrc_resource.cpp is attempted to be 
generated by both executable dependencies at once.

Not sure what is going on, but wondering if there was any advice out there for 
this problem
