You are trying to install into /usr/local, which probably is probably
write protected by normal users. You'll need to run 'sudo make
install' at this stage. Unless you aren't meaning to install into
/usr/local, which case, you should rerun cmake and pass it the
appropriate -DCMAKE_INSTALL_PREFIX value.
