Error in make install: "cannot copy file"

Try sudo make install.

To access the /usr directory of your installation to store system-wide files there, the installer needs root privileges. Therefore you can not just run plain make install as your normal user account but need to use sudo to elevate privileges.

If want to install without root / sudo try DCMAKE_INSTALL_PREFIX option:

mkdir -p $HOME/opt
cmake -DCMAKE_INSTALL_PREFIX=$HOME/opt .
make
make install

Consider adding folder to PATH, in order to use it by name only

export PATH="$HOME/opt/bin:$PATH" # for binaries
export LD_LIBRARY_PATH="$HOME/opt/lib:$LD_LIBRARY_PATH" # for libs
export CPATH="$HOME/opt/include:$CPATH" # for includes
