#     Automate the use of CMake, SWIG, Doxygen, Sphinx, and distutils
#     to build and install the GPSTK C++ Library, C++ Applications,
#     Python bindings, and documentation.

purpose:   This script automates and documents how to build, test, and install the GPSTk.

usage:     $0 [opts] [-- cmake options...]

examples:
   $ build.sh        # Just build software
   $ sudo build.sh -s -b /tmp/qwe    # Build and install core to $system_install_prefix
   $ build.sh -tue     # Build, test and install core, external, and python bindings to $gpstk
   $ build.sh -vt  -- -DCMAKE_BUILD_TYPE=debug   # build for running debugger
   $ build.sh -vt  -- -DCMAKE_BUILD_TYPE=release # build for release
   # MUST choose release to get -O3 optimization on linux

OPTIONS:

   -h                   Display this help message.

   -b <build_path>      Specify the cmake build directory to use.

   -i <install_prefix>  Install the build to the given path.

   -j <num_threads>     Number of threads to have make use. Defauts to $num_threads
                        on this host.

   -c                   Clean out any files in the build dir prior to running cmake.

   -d                   Build documentation, including generate dependency graphs
                        using GraphViz (.DOT and .PDF files).

   -e                   GPSTk has several parts: core, ext, and python/swig bindings.
                        See README.txt for details.
                        Default (without -e) will build only core
                        Optional (with -e) will build core, ext, and swig

   -u                   Install the build to the path in the \$gpstk environment variable.
                        If this variable is not set, it will be installed to
                        $user_install_prefix.

   -s                   Install the build into $system_install_prefix and the python
                        bindings to the default system location. Make sure the build path
                        is writable by root.

   -x                   Disable building the python bindings. Default is to build them
                        if -e is specified.

   -n                   Do not use address sanitizer for debug build (used by default)

   -P  <python_exe>     Python executable used to help determine with python system libraries
                        will be used when building python extension package.
                        Default=$python_exe

   -t                   Build and run tests.
   -T                   Build and run tests but don't stop on test failures.

   -g                   Compile code with gcov instrumenation enabled.

   -p                   Build supported packages (source, binary, deb,  ...)

   -v                   Include debugging output.
