[CMake] hanging/memory leak

[Matthew E. Pollack]

I am currently experiencing a strange behavior from cmake 2.0.5 
installed on a few linux boxes.  My CMakeLists.txt file is fairly 
straightforward and works fine.  That is, until I remove a "FORCE" 
directive from one "SET" line.  I have included the line below.  What 
really strikes me as odd, is that there is a nearly identical line just 
above the problem line, which does not have "FORCE" in it.  Without 
"FORCE" on this particular line, cmake and ccmake get through the "Check 
for working CXX compiler: c++ -- works" step, but then hangs, while 
eating memory at a rate of approximately 15 megs/minute.  Anyone have 
some ideas?  Shouldn't this work just fine?

Thanks,
    Matthew

Excerpt from CMakeLists.txt:

#######################
# Directory Variables #
#######################
#  Set the path to the  include directory
# THIS LINE WORKS FINE
SET (FMS_SI_INCLUDE_DIR ${CMAKE_SOURCE_DIR}/src CACHE PATH "Path to the 
Include Base Directory.")

#THIS LINE IS BROKEN
SET (FMS_SI_SOURCE_DIR ${CMAKE_SOURCE_DIR}/src CACHE PATH "Path to the 
Source Base Directory.")
