Subject: [babel] dynamic linking in user directory not working for C++ language

Hello everyone :)

I have a problem that I cannot fix when compiling a C++ source block.

My code block use several libraries and especially one named 
libarmadillo.dylib which is installed in a non-default place.

My code compiles well in the buffer shell of emacs with :
g++ -I/Users/benoitbayol/libs/include 
/Users/benoitbayol/libs/lib/libboost_system.a 
/Users/benoitbayol/libs/lib/libboost_chrono.a 
/Users/benoitbayol/libs/lib/libboost_thread.a 
-L/Users/benoitbayol/libs/lib -larmadillo main.cpp

but if I copy paste these flags and put them in :
#+begin_src C++ flags : -I/Users/benoitbayol/libs/include 
/Users/benoitbayol/libs/lib/libboost_system.a 
/Users/benoitbayol/libs/lib/libboost_chrono.a 
/Users/benoitbayol/libs/lib/libboost_thread.a 
-L/Users/benoitbayol/libs/lib -larmadillo

The compilation process with babel complains about a dylib 
(libarmadillo.3.dylib) which cannot be found with :
dyld: Library not loaded: libarmadillo.3.dylib
   Referenced from: 
/var/folders/xh/vvf5bjg15c3_rn5kdb4d2lk40000gn/T/babel-329218a6/C-bin-32921x5m
   Reason: image not found

In the /Users/benoitbayol/libs/lib folder I have
-rwxr-xr-x   1 benoitbayol  staff     41592 28 jan 14:03 
libarmadillo.3.92.2.dylib
lrwxr-xr-x   1 benoitbayol  staff        25 28 jan 14:03 
libarmadillo.3.dylib -> libarmadillo.3.92.2.dylib
lrwxr-xr-x   1 benoitbayol  staff        20 28 jan 14:03 
libarmadillo.dylib -> libarmadillo.3.dylib

I tried to fix my .emacs with (setq org-babel-C++-compiler "g++ 
-L/Users/benoitbayol/libs/lib") but I doesn't work.

Does anybody have an idea ?

Thanks :)
