Installation error

[lensofq]

Hello, I am trying to build ANTs on Mac , following the steps on GitHub instructions.
During the build step
make 2>&1 | tee build.log

I am encountering this error:
CMake Error at Examples/cmake_install.cmake:41 (file):
file cannot create directory: /opt/ANTs/lib. Maybe need administrative
privileges.
Call Stack (most recent call first):
cmake_install.cmake:42 (include)

make: *** [install] Error 1

How do I resolve this error?

This can be resolved by setting CMAKE_INSTALL_PREFIX to somewhere you can write.
