Using Quantlib in shinyapps

[galen211]

I'm unable to deploy an app I've built using RQuantLib to shinyapps.io. The error message I get when deploying is:

checking for quantlib-config... yes
configure: WARNING: RQuantLib requires QuantLib (>= 1.14).
configure: error: Please upgrade to a current version.
ERROR: configuration failed for package ‘RQuantLib’

I've consulted the [https://docs.rstudio.com/shinyapps.io/appendix.html#default-system-packages](Shiny Default System Packages Documentation), and I believe the issue could be solved by updating the below packages:

libquantlib0-dev                       1.7.1-1                               amd64        Quantitative Finance Library -- development package
libquantlib0v5                         1.7.1-1                               amd64
