Thank you very much for the detailed description of the problem.
For now, since you've installed the OpenMP runtime compatible with the
new Xcode version you're running, you can tell data.table to use it by
setting
Sys.setenv(PKG_LIBS = '/usr/local/lib/libomp.dylib')
install.packages('data.table', type = 'source')
...but be very careful not to use this build of data.table together in
the same session with other packages that use OpenMP. (You can
reinstall them from source in a similar manner to ensure that they are
compatible. Fortunately(?), almost no R packages on CRAN use OpenMP on
MacOS.)
Meanwhile, we'll need to figure out why the configure test fails when
CRAN builders compile data.table for macOS.
