How about invoking add_executable ten different times with the same source
code but different target names and different OUTPUT_NAME's?  Sure, that is
inefficient, but sometimes you have to make compromises to get stuff to work
with CMake, and you may not even notice the 9 extra compilation and link times.

Actually, that might be a better idea if you don't like the above
inefficieny.  I have no windows experience, but there is a cmake -E
create_symlink subcommand which I presume emulates symlinks on windows
(using copy or whatever).  So all you would have to do is to create 10
different custom targets using

COMMAND ${CMAKE_COMMAND} -E create_symlink old new

then run install (TARGET ...) for each of those targets.

There might also be some possibilities with the install(SCRIPT ...) or
install(CODE ...) signatures of the cmake install command.

Anyhow, I am just trying to give you some ideas here, and you will have to
experiment a little to see what is right for your needs.
