Standalone CMake Functions

Function	Base link set
`add_milk_standalone()`	milkfps, milkfpsStandalone, milkfpsseq, milkdata, milkprocessinfo, ImageStreamIO, COREMODmemory, COREMODtools, COREMODarith, COREMODiofits (USE_CFITSIO)
`add_cacao_standalone()`	same as above
`add_cacao_standalone_plugins()`	above + selected plugin libs

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: add_milk_standalone() / add_cacao_standalone() apply -DMILK_NO_CLI to the standalone executable target, redirecting CLIcore.h to the CLIcore_standalone.h stub for that target, which does some placeholding.

When USE_STATIC_LTO=ON, _static-suffixed static archives (e.g. milkCOREMODmemory_static) of these libraries are linked instead, enabling cross-module Link-Time Optimization. See PGO & LTO.
