[PATCH setup] add --build-depend option

Hello,

This patch adds an option --build-depend that, when called; installs the
packages listed in the build-depends property of setup.ini. It is for
someone who wants to build the binaries of a package themselves, enabling
them to pass one stringed package in lieu of a vector of packages.

Right now this is more or less a rough draft as feedback requested i.e.
what's the best way to implement this, and to get specific detailed
hand-holding help on two things (unless better approach):
 1. Using the correct setup.ini file (debugged using copy of setup.ini) and
    passing it as a string to the "stream" parameter of build_depend(), which
    is declared as:
    - std::string build_depend(std::string pkg_search, std::string stream)
    in build_depends.h.

 2. Convert and handle successful output of build_depend(), passing it to
    "PackageOption" in package_meta.cc (unless better way) as a vector as
    if the output from build_depend() was passed to -P, --packages.

Currently only the results are output to the Cygwin terminal, but from
the several
commands I've tested (see bottom); the output seems good. The process I have
in mind is:
   I. --build-depend <package> == true
  II. <package> is searched in setup.ini
 III. if <package> found and has "build-depends" property, then send an array
      of packages to be used by -P, --packages, else some not found message.

So essentially if, e.g.
`setup -q --build-depend cxsparse-debuginfo`,
then the process will run as if,
`setup -q -P cmake,cygport,gcc-fortran,liblapack-devel,libmetis-devel,libopenblas,libsuitesparseconfig-devel,pkg-config`
were called. But I'm not sure if this is the best approach.

If it is, though; then what remains:
 1. Correct use of setup.ini, converting identified file to string so
it can be passed
     to build_depend().
 2. Convert build_depend() output to vector and use that to create
    "PackageOption" class.

Additional Quasi-JSON Info:

  syntax: setup [-q] --build-depend <package>,
