+\subsection options_smpi_privatize_libs smpi/privatize-libs: Automatic privatization of
+ global variables inside external libraries
+
+Linux/BSD only : When using dlopen (default) privatization, privatize specific 
+shared libraries with internal global variables, if they can't be linked statically. 
+For example libgfortran is usually used for Fortran I/O and indexes in files 
+can be mixed up.
+
+\warning
+  This configuration option can only use either full paths to libraries, or full names.
+  Check with ldd the name of the library you want to use.
+  Example :
+  ldd allpairf90 
+    libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3 (0x00007fbb4d91b000)
+  Then you can use --cfg=smpi/privatize-libs:"libgfortran.so.3" or --cfg=smpi/privatize-libs:"/usr/lib/x86_64-linux-gnu/libgfortran.so.3", but not "libgfortran" or "libgfortran.so".
+  Multiple libraries can be given, semicolon separated.
