Hi Paul,

Thank you for the patch.

You're in the libcamera namespace, so there's no need for libcamera::.

I expect other IPA modules to need the same install_dir. How about

ipa_install_dir = join_paths(get_option('libdir'), 'libcamera')

ipa_dummy = shared_library('ipa_dummy',
...
                           install_dir : ipa_install_dir)

And here

             '"' + join_paths(get_option('prefix'), ipa_install_dir) +'"')

With this fixed,
