- since the Apple SIP (System Integrity Protection) clears environment
variables such as DYLD_LIBRARY_PATH, a number of workarounds have
been used to provide shadow values. However, for a more robust
installation using -rpath at compilation time appears to be the
better solution.
In addition to the usual -rpath specification with absolute file
paths, MacOS supports (@loader_path, @executable_path) as well.
Now default to link with rpath information for MacOS, which can be
disabled by adding `~rpath` in WM_COMPILE_CONTROL
Explicit library paths handled:
- FOAM_FOAM_EXT_LIBBIN, FOAM_EXT_LIBBIN/FOAM_MPI
The executable rpaths are handled assuming a structure of
install-path/bin
install-path/lib/$(FOAM_MPI)
install-path/lib
Absolute compile-time paths for FOAM_USER_LIBBIN, FOAM_SITE_LIBBIN
and FOAM_LIBBIN are not handled since these are either too fragile
(FOAM_USER_LIBBIN and FOAM_SITE_LIBBIN values) or covered via
@loader_path anyhow (FOAM_LIBBIN).
Since the value of FOAM_MPI is a compile-time value, this rpath
treatment makes the installation less suitable for runtime changes
to the MPI vendor/version.
Note: no rpath added for c-only compilations since there are
currently no c-only libraries or executables with dynamic loading
