usage: configure {options}
Configure the POCO C++ Libraries.

Options:
  --help
    Display this help screen.

  --config=<config_name>
    Use the given build configuration.
    Available configurations are:

`ls -C $base/build/config/`

  --prefix=<install_prefix>
    Use the given install directory for make install.
    Default is /usr/local.

  --no-prefix
    Do not use /usr/local as default install directory and do not
    define POCO_PREFIX.

  --stdcxx-base=<apache_stdcxx_install_prefix>
    If (and only if) the $base/build/config selected with --config
    uses the Apache stdcxx library, then apache_stdcxx_install_prefix
    specifies the base directory where stdcxx is installed.

  --no-tests
    Do not build testsuites.

  --no-samples
    Do not build samples.

  --minimal
    Build only Foundation, XML, JSON, Util and Net.

  --typical (default)
    Build only Foundation, XML, JSON, Util, Net, Crypto, NetSSL, Data/SQLite and Zip.

  --everything
    Build everything.

  --no-wstring
    Compile with -DPOCO_NO_WSTRING.
    Useful if your C++ compiler does not support std::wstring
    (such as uClibc-based systems).

  --no-fpenvironment
    Compile with -DPOCO_NO_FPENVIRONMENT.
    Useful if your C++ compiler has incomplete floating-point support
    (such as uClibc-based systems).

  --no-sharedmemory
    Compile with -DPOCO_NO_SHAREDMEMORY.
    For systems that don't support shared memory API's,
    like uClibc-based Linux systems.

  --no-sharedlibs
    Compile with -DPOCO_NO_SHAREDLIBS.
    For systems that don't support shared library loading.

  --no-ipv6
    Compile with -DPOCO_NET_NO_IPv6.
    For systems that don't support IPv6.

  --sqlite-fts=<path>
    Compile with -DPOCO_DATA_SQLITE_FTS.
    Compile SQLite with Full Text Search support.

  --sqlite-thread-safe=<value>
    Compile with -DSQLITE_THREADSAFE=<value>.
    Valid values are:
		- 0 single-thread, no thread safety
		- 1 serial access, highest thread safety
		- 2 multi-threaded, without session sharing support


  --omit=<component>{,<component>}
    Do not build the specified component(s).
    Example: --omit=Data/MySQL,Data/ODBC,Zip

  --include-path=<path>
    Add search path for header files.

  --library-path=<path>
    Add search path for library files.

  --odbc-lib=<path>
    Specify the directory where ODBC library is located.

  --odbc-include=<path>
    Specify the directory where ODBC header files are located.

  --cflags=<flags>
    Pass additional flags to compiler.
    Example: --cflags=-wall

  --poquito
    Omit a few features for smaller codesize when linking
    statically for embedded targets.

  --unbundled
    Use system-provided zlib, pcre, expat and sqlite instead of
    bundled ones.

  --static
    Build static libraries. Overrides default mode, which
    depends upon target. Can be specified together
    with --shared to build both.

  --shared
    Build shared libraries. Overrides default mode, which
    depends upon target. Can be specified together
    with --static to build both.
