Look at the attached exemplary CMakeLists.txt file. However, note that
- changing the CMAKE_INSTALL_PREFIX means invalidating the build tree,
so the whole project is built anew when install-update is triggered,
- triggering install-update means rebuilding *and* installing, so you
possibly need root privileges for this to succeed; building as root
is inadvisable, so you should perhaps limit yourself to a target
"build-update" without the install step and run "make install"
in the end as usual.
'hope that helps.
