RQuantLib won't load when deploying a shiny app - r

Question

I am having an issue when deploying a shiny app that requires the package RQuantLib. When I'm running my application, everything works fine, even the part where the RQuantLib package is needed. However, when deploying the application, the process is stopped when building the package RQuantLib.
When I put into comments the line "library(RQuantLib)" the application can be deployed but I am obviously missing my parts based on the use of this package.
Here's the error :

Thank you in advance !

RQuantLib author here. I actually try to make this as plain as I can:
configure: WARNING: RQuantLib requires QuantLib (>= 1.8.0).
configure: error: Please upgrade to a current version.
ERROR: configuration failed for package ‘RQuantLib’
Also not sure what system you are on (as you didn't say) but both Debian and Ubuntu
have RQuantLib natively: sudo apt install r-cran-rquantlib is all it takes.
Otherwise it may be worth re-stating the somewhat obvious: to build RQuantLib from source you need both R and QuantLib on the system you are building (== installing) on if you install from source. Hence the attractiveness of installing binaries -- which I provide as Debian maintainer.
