It is because CMake does not handle Compaq fortran.
It detects the compiler (f90.exe) but there is nothing indicating to cmake
how to deal with it so it falls back to 'standard' options (-o instead 
of /out:).

To allow CMake properly configuring itself to use Compaq Fortran, you have
to put a file named Windows-f90.cmake in the Platform subdirectory
of the Module directory (in CMake Installation) or of a directory
defined in CMAKE_MODULE_PATH.

Attached, you have one I wrote to correctly set the parameters for 
compaq f90 (I
expect so :)).
However, now there is another problem with, I think, '/' put in paths 
instead of '\'
and f90 does not like at all, thinking that it is options.
At now I do not have time to investigate more (see my thread
"Compaq Fortran 6.1 detection fails under Windows" sent during june) it is
why I did not give the solution.
