Cannot build on Fedora32

[andrewdavidmackenzie]

I'm trying to build on Fedora32 and it cannot find libappindicator3:

--- stderr
thread 'main' panicked at 'libappindicator3 library not found!', /home/andrew/.cargo/registry/src/github.com-1ecc6299db9ec823/libappindicator-sys-0.5.0/build.rs:35:23
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

warning: build failed, waiting for other jobs to finish...
error: build failed

But I already have it and devel package installed:

sudo yum install libappindicator-gtk3

Any suggestions?
