How to use add_deps when I set prefixname as empty?

[sndth]

target("libtest")
  -- set
  set_kind("static")

  -- add
  add_files("libtest/*.cpp")
  add_headerfiles("libtest/*.h")
target_end()

This code will generate liblibtest.a on Linux, so to fix typo (double lib keyword) I added:
set_prefixname("")

But now I can't use add_deps:

add_deps("libtest")

I renamed deps like in this message:

error: /usr/bin/ld: cannot find -llibtest: No such file or directory
/usr/bin/ld: note to link with build/linux/x86/release/libtest.a use -l:libtest.a or rename it to liblibtest.a

But still I can't compile source.

use set_basename("test")

Thank you!
