permissions - How to preserve ownership with cmake "install directory" directive? -

use_source_permissions preserves permissions expected:

install(   directory dir/   destination dest   use_source_permissions ) 

however, ownership of files not preserved when run

sudo make install 

am missing something, or there's no way of accomplishing cleanly cmake?

edit:

• cmake version 3.5.2
• operating system arch linux

i came simplest example think of reproduce issue , still, same happening.

cmake_minimum_required(version 2.8 fatal_error)  install(directory ${cmake_current_source_dir}/to_install         destination $env{home}         use_source_permissions) 

then run:

mkdir build cd build cmake .. sudo make install 

the original permissions are:

.──[drwxr-xr-x guicc   ]  test-cmake    ├── [-rw-r--r-- guicc   ]  cmakelists.txt    └── [drwxr-xr-x guicc   ]  to_install        ├── [-rw-r--r-- guicc   ]  file1.txt        └── [-rw-r--r-- guicc   ]  file2.txt 

while resulting permissions following:

.──[drwxr-xr-x root   ] to_install    ├── [-rw-r--r-- root    ]  file1.txt    └── [-rw-r--r-- root    ]  file2.txt
