add_cacao_standalone_plugins(name src.c)               # all 4 plugins
add_cacao_standalone_plugins(name src.c fft imagegen)   # selective

Valid plugin names: fft, imagegen, imagefilter, imagebasic.

ℹ️ Note: _compute variants contain pure computation code (MILK_NO_CLI). Standalone executables do not link ${LIBNAME} by default. Currently 76 of 90 standalones are CLIcore-free.

When USE_STATIC_LTO=ON, static archive (.a) variants of these libraries are built and linked instead, enabling cross-module Link-Time Optimization. See PGO & LTO.
