Following Vignette Results in Package With 2 Warnings and 1 Note

Mainly a quality of life request. Working on a package use rextendr that we hope to submit to CRAN, I know they are strict about warnings. If I do` ```R usethis::create_package("mypack") rextendr::use_extendr() devtools::check() ``` I get: ``` ❯ checking top-level files ... WARNING A complete check needs the 'checkbashisms' script. See section ‘Configure and cleanup’ in the ‘Writing R Extensions’ manual. ❯ checking Rust compilation ... OK WARNING ‘qpdf’ is needed for checks on size reduction of PDFs ❯ checking compilation flags used ... NOTE Compilation used the following non-portable flag(s): ‘-mno-omit-leaf-frame-pointer’ ``` Will work to get these resolved in the package I'm working on, but would be nice if the default setup was clean.
