What's interesting is that in a project that's fully update to date,  
running the make modules command gives this curious output:

S896822:tools kbelco$ make modules
[ 16%] Built target util
[ 19%] Built target tp
[ 25%] Built target spr
[ 35%] Built target rn2
[ 61%] Built target rn1
[ 61%] Built target mp
[100%] Built target modules

which is the same list of libraries in these SUBDIRS commands in the  
top-level CMakeLists.txt file (in reverse order).  There's a single  
library in each of these subdirs of the same lower-cased name.

...
SUBDIRS(Modules)
SUBDIRS(MP)
SUBDIRS(Rn1)
SUBDIRS(RN2)
SUBDIRS(SPR)
SUBDIRS(TP)
SUBDIRS(Util)

So it looks like the subdirs command plays a role in this behavior.
