data.table does not find openmp support

Naresh Gurbuxani <naresh_gurbuxani at hotmail.com> ?????:

Sys.setenv(PKG_LIBS = "/usr/local/lib/libomp.dylib")
Sys.getenv("PKG_LIBS")  

[1] "/usr/local/lib/libomp.dylib"

install.packages("data.table", type = "source")  

Sorry, I forgot that the "checking if R installation supports OpenMP
without any extra hints" test only happens on Linux. Looks like the
current ./configure will always add -lomp to PKG_LIBS and break the
build unless you're running Xcode <= 16.2.

If you're interested in testing a development version of data.table,
could you please try compiling from the 'fix-macos-15-image' branch?
