Package 'ompdetect'

Title: Example Configure Test for 'OpenMP'
Description: Best practices for cross-platform 'OpenMP' support in an R package. On most platforms, use the R-provided Make macros. On macOS, test the pre-set environment variables, the CRAN builder configuration, the R-provided Make macros (which may be set when using a custom toolchain that supports OpenMP), and the custom OpenMP installation path (when mixing a CRAN build of R with an incompatible Xcode version).
