Thanks for filing this. I ran into the same issue. As a workaround I added an .envrc like this so https://direnv.net/ can point cdktf to the asdf-provided binary.

export TERRAFORM_BINARY_NAME="$(asdf which terraform)"

I also opened https://github.com/asdf-community/asdf-hashicorp/issues/64 for consideration in the asdf plugin.

@ansgarm just noticed your docs comment (separate issue), there is an example here https://github.com/damianoneill/cdk if it helps.
