You can specifiy the generator on the command line with a -G"...".
I belive we have done all of the above, except for Watcom.

Right now, cmake does not support fortran directly.   You would
have to use a custom command to do this.   See the FAQ entry
about building LaTex.   Fortran would have to be done in a similar way.
For real fotran support, the depend generator and the makefile generators
would have to be changed.

The ADD_CUSTOM_COMMAND would be the way.

With visual studio 6 and 7, you can do it from the IDE.
With the make based makefiles, you specify debug or release
with cmake.  See the CMAKE_BUILD_TYPE cache entry.

Right now that is not possible.    There are some issues having to do with paths.
The compilers require and support different path types.   g++/gmake with cygwin
supports/expects cygwin paths.   cl will not support cygwin paths.

Sounds great, we would be happy to incorporate your additions once they are tested.
For 5, you will want to start in Source/cmake.cxx and add the UnixMakefileGenerator
as an option for all the builds, and see how far you get.
