Hi all

I need to run a command with install(CODE “…”) when generating my .deb with make package.  
For this command I need to know the path of the temporary install made by cpack.  
It seems to be in \_CPack\_Packages/Linux/DEB/ but is there a variable to read it ?  
I though CMAKE\_INSTALL\_PREFIX would be modified (with \ before ${CMAKE\_INSTALL\_PREFIX }) but with or without CPACK\_SET\_DESTDIR on the variable is always the finale destination folder (/opt/something).

Is there a way inside install(CODE “…”) to get the temporary cpack install folder ?

Thanks

`$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}`
