\`configure' configures Boost to adapt to a few kinds of systems.
Usage: $0 [OPTION]...
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--with-bjam=BJAM use existing Boost.Jam executable (bjam)
[automatically built]
--with-toolset=TOOLSET use specific Boost.Build toolset
[automatically detected]
--show-libraries show the set of libraries that require build
and installation steps (i.e., those libraries
that can be used with --with-libraries or
--without-libraries), then exit
--with-libraries=list build only a particular set of libraries,
describing using either a comma-separated list of
library names or "all"
[all]
--without-libraries=list build all libraries except the ones listed []
--with-icu enable Unicode/ICU support in Regex
[automatically detected]
--without-icu disable Unicode/ICU support in Regex
--with-icu=DIR specify the root of the ICU library installation
and enable Unicode/ICU support in Regex
[automatically detected]
--with-python=PYTHON specify the Python executable [python]
--with-python-root=DIR specify the root of the Python installation
[automatically detected]
--with-python-version=X.Y specify the Python version as X.Y
[automatically detected]
Installation directories:
--prefix=PREFIX install Boost into the given PREFIX
[/usr/local]
--exec-prefix=EPREFIX install Boost binaries into the given EPREFIX
[PREFIX]
More precise control over installation directories:
--libdir=DIR install libraries here [EPREFIX/lib]
--includedir=DIR install headers here [PREFIX/include]
