Maybe more correct
On raspberry pi debian 12, when trying to build
https://codeberg.org/flyxyz123/remote_plot, I got make error "ld:
undefined reference to ..." if use `cc -Wall $$(pkg-config --cflags
--libs libssh plplot gtk4) -lm -o $@ $^`. No error if move $^ to the
beginning. Not sure why, maybe becuase pi has an old version of gcc?
This repo does not have this issue if put `$^` at the end. But I think
put `$^` at the beginning maybe is a more correct way.
