The problem I was having was whether an argument with spaces was
getting passed in as one or two arguments.  Something like that would
be hard to detect printing it with message().

I actually ended up writing a helper executable that printed out all
the arguments and using that in place of cmake when invoking.

#include <stdio.h>

int main(int argc, char* argv[], char* env[])
{
  int i;
  for(i = 0; i < argc; ++i)
    printf("arg[%d] = %s\n", i, argv[i]);
#if 0
  for (i=0; env[i]; ++i)
    printf("env[%d] = %s\n", i, env[i]);
#endif

  return 0;
}
