But in this case I get two build directories for each subproject (simplified
paths, add Debug/Release for each):
- one in /builds/main_project/subproject_NN when building the top-project,
- one in /builds/subproject_NN when building each of the sub-projects
...by default.

Of course I can go through each subproject opened separately and point the
build directory to the sub-main one. But that is *really* cumbersome...

More specifically, what I would like is:
- if I ask to build the top-project, all the sub-projects are build
   --> this is the current behaviour, perfect
- if I ask to build one of the sub-project, only this one is build
   --> this is the current behaviour, perfect
- if I ask to *run* the top-project, all the sub-projects are build
   --> this is the current behaviour, perfect
- if I ask to *run* one of the sub-project, only this one should be
   build if necessary
   --> not the current behaviour, all subprojects are build (or checked
     at least)

To put this in context, I'm talking here about more than 150 sub-projects:
opening them one by one is tedious.
Indeed the "-j" switch helps, but not that much, and it's not relevent
when using "nmake" (yes I know about "jom", which can't be used sometimes
for some obscure internal reason).

To avoid the doubled build directory, I found a rather easy way:
- launch QtCreator, set default build directory to
   ../builds/%{CurrentProject:Name}-%{CurrentKit:FileSystemName}-%{CurrentBuild:Name}
- open and configure the top-project, build it (takes a long time)
- set default build directory to
   ../../builds/topproject-%{CurrentKit:FileSystemName}-%{CurrentBuild:Name}/%{CurrentProject:Name}
- open and configure each sub-project

At least the bunch of subprojects can be build in one go and don't have to be rebuild
when opening each one :-)
