I put your 2 lines into a file called glob.cmake.  Then I ran it as a
script, using a Windows Vista Command Prompt.  I got the following
results:

C:\devel\src\cbugs\glob>cmake -P glob.cmake
CMake Error: Error in cmake code at
C:/devel/src/cbugs/glob/glob.cmake:3:
message called with incorrect number of arguments
   Called from: [1]     C:/devel/src/cbugs/glob/glob.cmake

C:\devel\src\cbugs\glob>

Thus: the glob expressions didn't match anything in my current
directory, BLITZ_TMP was null, and MESSAGE fails because it has been
handed no arguments.  Generally you need MESSAGE("${myvariable}").

When I include the glob.cmake in a CMakeLists.txt, CMakeSetup crashes
as you described.  I am wondering why CMakeSetup can't be more
informative about the error.
