compilation failed with symbol multiply defined! failed to load bitcode of module "program nane-xxx"

[SpringChiu]

when I import solana anchor program's instruction, compilation failed with error info:
those are my code:

use solana_vault::instruction as solana_vault_instruction;

those are error info:

warning: Linking globals named 'entrypoint': symbol multiply defined!

error: failed to load bitcode of module "solana_vault-91162013c3821f80.solana_vault.c7fe4af8e94c9c31-cgu.0.rcgu.o":

You can fix this by enabling either the cpi or the no-entrypoint feature of the external program crate you're using. For example:

[dependencies]
solana-vault = { version = "0.1.0", features = ["cpi"] }

You can also avoid adding programs for CPI as a dependency by using declare_program!.

Thanks! I add feature of no-entrypoint and it compiled success
