Domen Vrankar deeba85f81 CMake: enable setting default dir creation permissions 
Introduces CMAKE_DEFAULT_DIRECTORY_INSTALL_PERMISSIONS
variable which enables the user to specify the default
permissions for directory creation. This setting is then
used to auto set the permissions on directories which
are implicitly created by install() and file(INSTALL)
commands such as CMAKE_INSTALL_PREFIX directories.
