Thanks for your response, I'll open the feature request. I tried the 
second work around (I can't get all of my users to use that environment 
variable from the first case).  Unfortunately it doesn't seem to be working:

 From CMake output:
-- The C compiler identification is VisualAge
-- The CXX compiler identification is VisualAge
-- Check for working C compiler: /usr/bin/mpcc
-- Check for working C compiler: /usr/bin/mpcc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/bin/mpCC
-- Check for working CXX compiler: /usr/bin/mpCC -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- CMAKE_C_ARCHIVE_CREATE = <CMAKE_AR> -X 64 cr <TARGET> <LINK_FLAGS> 
<OBJECTS>
-- CMAKE_C_ARCHIVE_APPEND = <CMAKE_AR> -X 64 r  <TARGET> <LINK_FLAGS> 
<OBJECTS>
-- CMAKE_C_ARCHIVE_FINISH = <CMAKE_RANLIB> <TARGET>
<snip>

Then, during make VERBOSE=1:
Linking CXX static library libHpmi.a
      cd /scr/dicharry/ICEPIC/BuildArea/hpmi/src/hpmi && 
/site/PET/pkgs/cmake-2.6.4/bin/cmake -P

         cd /scr/dicharry/ICEPIC/BuildArea/hpmi/src/hpmi &&

Thanks again,
