Title: Unable to install using alternate BOOST path

Hello,

I am attemting to install CGAL 3.3.1 in an environment where BOOST is in a non-standard location. Reading the top of the install_cgal script, I see a mechanism that appears to be designed to support this scenario. Under "advanced options", there is:

  --PACKAGENAME_INCL_DIR <dir>
               Add \"-I<dir>\" to CPPFLAGS. The valid PACKAGENAMEs in this
               context are BOOST, BOOST_PROGRAM_OPTIONS, BOOST_BIMAP, X11,
               GMP, GMPXX, MPFR, ZLIB, BLAS, LAPACK, LEDA, LEDAWIN, OPENGL,
               QT, TAUCS

To me, this says "if you specify --BOOST_INCL_DIR <dir> on the invocation line, then \"-I<dir>\" will be added to the command when the C++ compiler is invoked."

I tried this but it did not work. Here is how install_cgall was invoked:

$ ./install_cgal.copy --prefix=/cygdrive/c/Program\ Files/CGAL --BOOST_INCL_DIR "h:\downloaded\BOOST\boost_1_34_0"

(This is under cygwin running under Windows XP, with the target compiler Visual C++ 8. I am using the script install rather than the installer application because I am hoping to understand the changes made for installation. The overall goal  is to fit the CGAL installation into a larger build process for the application that uses it, and to make that work I need to see what it does.)

From install.log (after enabling INSTALL_VERBOSE):

Testing support for BOOST ...
    OK: requirements and incompatibilities.

Failed: BOOST test program.

As you can see, \"-I<dir>\" was not added to the command line. Have I named the option incorrectly, or perhaps misinterpreted its intention? I have done some tracing of install_cgal to try to understand the problem, but the way the command line is built is pretty intricate and as a result this tracing is very time consuming. From what I've found, I am pretty sure I could accomplish my goal by modifying STDINCLDIRS in H:\downloaded\CGAL\CGAL-3.3\CGAL-3.3.1\config\support\S05-BOOST, but that would be a hack and I'd prefer a clean solution, espcially since there seems to be a mechanism designed to accomplish this goal.

FYI I also tried specifying a unix-style path instead of a windows-style path, but that made no difference.

Thank you in advance for your help.
