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.

  --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.

  --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).

  --disable-NetSSL
    Do not build NetSSL support

  --disable-Data
    Do not build Data support

  --disable-ODBC
    Do not build Data/ODBC support

  --disable-SQLite
    Do not build Data/SQLite support

  --disable-MySQL
    Do not build Data/MySQL support
