Following that link, there is a nice example of installing files
outside /usr in an rpm.

esjolund at otto:/tmp/y$ rpm -qlp /tmp/y/myscript-1.0.rpm 
/opt
/opt/sbin
/opt/sbin/myabsolutescript
/usr
/usr/local
/usr/local/sbin
/usr/local/sbin/myscript

But if I have an additional requirement that a normal user should be
able to install the software in his home directory like this,

cmake -DCMAKE_INSTALL_PREFIX=/home/erik /tmp/myscript-1.0-src && make &&
make install

I get the error:

----------
CMake Error at cmake_install.cmake:40 (FILE):
  file cannot create directory: /opt/sbin.  Maybe need administrative
privileges.
----------

Is there a way to a the same time fullfill these needs?
* the need to install files outside /usr in an rpm 
* the need for a non-root user to be able to install the software in his
home directory?
