C# Mono Compile with Libraries folder?

Question

I have a C# project like this:

root
|- libs
|  |- Compression.cs
|- test.cs

My compilation shell command is as follows:

mcs /out:test.exe *.cs

I'm getting the error message:

The type or namespace name `Compression' could not be found. Are you missing an assembly reference?

Any idea how I can tell mono to look in subfolders for C# libraries?

As Lex Li said in a comment on the question:

mcs /out:test.exe **/*.cs
