The 'make install' target could also be responsible for creating files which 
need to be deployed. I think installing to a tmp dir is the best solution.

I think you mean a step such as extracting an archive after the archive has 
been copied to the device?

Are you saying it is a problem for the deployment plugin to do

 DESTDIR=/tmp/foo make install

or 

 DESTDIR=/tmp/foo cmake -P cmake_install.cmake

?

It does have the problem of redundant maintanence of that file (manually).

CMake can't really just give you a list of files to install, because as I 
said above, some files don't exist until make install is run.

Thanks,
