Linux rpm instrument directory permission incorrect

[Anders-Markvardsen]

This issue was originally TRAC 5220

The linux rpm instrument directory permissions is not
writable to everyone. An effect of this is that .vtp
files cannot be written to this directory from an installed
version on Linux, and instead default to /tmp.

In cmake it is setup to be writable but somehow loses
this knowledge. Note this effect is only seen on Linux not Mac (or windows
for that matter).

Make this directory writable on linux also

Just a note: This is something to do with CPACK and is confined to the RPM. The debian installation has the permissions set correctly.

Looking at the directory structure you can see that the permissions are correct after CPack has generated the temporary structure it is only once it has been packaged that the RPM fails to set the correct permissions. This used to work.

No longer relevant. The directories are not writable but now the files go to the mantid user file directory.
