Please try out the patch below (applies to CMake from CVS HEAD).
With it, CMake should recognize the Compaq compiler out of the box.
It won't know what flags to use without the compiler info files, but
at least it should report the compiler identification.  If that works
for you I'll commit it upstream.  Then we can work on the compiler
info files.

Thanks,
