[GabrielLunesu]

gabriellunesu@Gabriels-MacBook-Air AdNavi % defang compose up --provider=gcp
! GCP provider was selected, but GCP_PROJECT_ID environment variable is not set

• Using Google Cloud Platform provider from command line flag
  Error: GCP_PROJECT_ID or CLOUDSDK_CORE_PROJECT must be set for GCP projects
  gabriellunesu@Gabriels-MacBook-Air AdNavi % defang config set GCP_PROJECT_ID
• Using Google Cloud Platform provider from stored preference
  Error: GCP_PROJECT_ID or CLOUDSDK_CORE_PROJECT must be set for GCP projects
  gabriellunesu@Gabriels-MacBook-Air AdNavi %

this is the output it gives when trying to deploy to gcp, it is not clear what i should do
