[R-pkg-devel] CRAN cannot find libraries on Windows

Hello all,

My package (source here <https://github.com/lucasnell/jackalope>) no longer
compiles on a standard Windows installation (see truncated install log
below). The problem seems to be the libraries required by the Bioconductor
package Rhtslib
<https://bioconductor.org/packages/release/bioc/html/Rhtslib.html>. My
package compiles fine when using GCC 8 via Rtools 40 (and when built using
"r-devel-windows-ix86+x86_64-gcc8" on CRAN), but when trying to submit a
new version to CRAN, it fails its automatic tests without working using GCC
4 on Windows. Does anyone have ideas on how to fix this? Thank you!

Cheers,
Lucas
