How I can let lspconfig to find my installed lsp servers in ~/.bin/ directory?

Hello, I installed all my lsp server bins in ~/.bin/ directory, but lspconfig complains that it cannot spawn a lsp server, so how can I tell lspconfig to find them in ~/.bin/ directory??

Thank you

Ran into similar issue with lsp binaries, using OS X my system shell is zsh and had to set the PATH in ~/.zprofile so neovim GUI could find those binaries.
