Wait, no. No, it's not. It's outputting exactly as it should.

If I do this in gnome-terminal, it works...

$ g++ -g -o base base.cpp `pkg-config gtkmm-3.0 --cflags --libs}`

I can run the call to pkg-config by itself, and I get the endless line
of options I expect.

If I run this in eshell, it doesn't work...

$ g++ -g -o base base.cpp ${pkg-config gtkmm-3.0 --cflags --libs}

I get "g++: error: unrecognized command-line option '...'"

With the enless line of options in quotes, but that's just the compiler
quoting at me.

If I do...

${pkg-config gtkmm-3.0 --cflags --libs}

In eshell, I get the same result as if I ran pkg-config in
gnome-terminal.

I'm even more confused.
