Lib:

module testlib;
static string abc = "Hello World!";

Source file:

module app;
import std.stdio;
import testlib;

void main()
{
    writeln(abc);
}

Dub:

{
	"authors": [
		"WJ"
	],
	"copyright": "Copyright © 2020, ME",
	"description": "The lib test",
	"license": "proprietary",
	"name": "app",
	"targetPath": "./bin/",
	"targetType": "executable",
	"importPaths": ["libs"],
	
	"lflags":["-L/home/aleksej/Programming/Tests/ldclibtest/libs"]
}

I get the error:

app ~master: building configuration "application"...

(Undefined link to testlib)

I also try to add:

"libs": ["testlib"]

But then i get:

89AF60F91654EFC94DCE63378DCD4/app .dub/build/application-debug-linux.posix-x86_64-dmd_v2.096.0-95A89AF60F91654EFC94DCE63378DCD4/app.o -L--no-as-needed -L-L/home/aleksej/Programming/Tests/ldclibtest/libs -L-ltestlib -g
/usr/bin/ld: невозможно найти -ltestlib

(Can't find -ltestlib)

What am I do wrong? How can I link my library with my app?
