Command to Install built plugin

is there a command to install plugin on your system via cmake
theres the COPY_AFTER_BUILD option in the juce plugin config
but if you’ve got build caching it wont copy/install (because nothing was rebuilt)

do I need to setup my own custom cmake install config?
I tried to run cmake --install build-dir and it installed the JUCE library to my system, instead of my plugin

I already acknowledged this option in the question
