It appears from your comments above that you are trying to install some
files in the system hierarchy (/usr/lib) and some files in some directory
(probably in /home/SomeUserName) which is normally writeable by a user
account.  The mixture of root and user account file installs is not
recommended since it violates the FHS standards (see
http://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard and links from
there).  Most Linux distributions follow the FHS so often you can figure out
where files should be installed by looking at what your distribution does
for similar files.

Once your installation conforms to the FHS, then all you have to do to make
it completely installable in a user account (with no root access needed) is
to change the -DCMAKE_INSTALL_PREFIX option for cmake.
