Hi,
I'm trying to publish my shiny application to shinyapps.io from my RStudio but getting error messages. The application is running fine in local environment. The errors are as given below -


checking for pkg-config... /usr/bin/pkg-config
checking if pkg-config knows NLopt... no
checking for cmake... no
