It is possible to rename file with qmake

[themean]

Hi
I want to create "make install" for my project. I use INSTALLS variable and all works fine but i want installed file to be renamed. How i can achieve this
I trying this

Install.path = path/for/installation
 
install.file = file.something
 
install.name = newname.somthingelse
 
INSTALLS += install

Install.path = path/for/installation

install.file = file.something

install.name = newname.somthingelse

INSTALLS += install

To copy to clipboard, switch view to plain text mode 

but this don't work. I know about install.extra but don't know how to use this variable
