No console output from Rust lib linked in MSVC++ app

We are linking a Rust static library into a Windows C++ app built with MSVC.
There is no console output from the Rust library.
Is there some cargo build setting we might be missing?

We are using cargo +stable-x86_64-pc-windows-msvc build to build the library, which outputs a .lib file. We also linking the following static libraries:

userenv.lib
ws2_32.lib
setupapi.lib

The console output we're expecting to see is from println! statements in the Rust code.
