[CMake] How not to copy a link

[Kevin Burge]

I'm trying to copy a file that is a link to another file, but I want the 
file to be copied, not the link itself.  Historically, I've resorted to 
putting the real file as the source, and then using RENAME to rename the 
file, which puts more detail into my install commands than I'd like.

Example:

where libfoo.so.1.0 -> libfoo.so.1.0.8:

i.e. instead of:

install (FILES libfoo.so.1.0.8 DESTINATION lib RENAME libfoo.so.1.0)

I'd like to just do:

install (FILES libfoo.so.1.0 DESTINATION lib)

I've had little success search the cmake source and documentation and 
google.

Thanks,
Kevin
