Unable to find cairo library when compiling with zig 0.7.0 and 0.7.1

[jackdbd]

On Travis CI and on my machine the project fails to build with zig 0.7.0 and 0.7.1 because of a linker error.

lld: error: unable to find library -lcairo
error: LLDReportedFailure
The following command exited with error code 1:

The command "zig build test" exited with 1.

The project builds succesfully with zig 0.6.0 and zig 0.8.0-dev.1032+8098b3f84.

All Travis jobs install the libcairo2-dev using the APT addon.
