COMMON_INFO="\"Source code of dependencies needed to be compiled will be downloaded and extracted into '\$SRC'.
Built libs of dependencies needed to be compiled will be installed into '\$INST'.
Please edit \\\$SRC and/or \\\$INST variables at the beginning of this script,
or use --source/--install options, if you want to use other paths!

Number of threads for building: \$THREADS (automatically detected, use --threads=<nbr> to override it).
Full install: \$WITH_ALL (use --with-all option to enable it).
Building OSL: \$WITH_OSL (use --with-osl option to enable it).
Building OpenCOLLADA: \$WITH_OPENCOLLADA (use --with-opencollada option to enable it).
All static linking: \$ALL_STATIC (use --all-static option to enable it).

Example:
Full install without OpenCOLLADA: --with-all --skip-opencollada

Use --help to show all available options!\""

ARGUMENTS_INFO="\"COMMAND LINE ARGUMENTS:
    -h, --help
        Show this message and exit.

    -s <path>, --source=<path>
        Use a specific path where to store downloaded libraries sources (defaults to '\$SRC').

    -i <path>, --install=<path>
        Use a specific path where to install built libraries (defaults to '\$INST').

    -t n, --threads=n
        Use a specific number of threads when building the libraries (auto-detected as '\$THREADS').

    --with-all
        By default, a number of optional and not-so-often needed libraries are not installed.
        This option will try to install them, at the cost of potential conflicts (depending on
        how your package system is set…).
        Note this option also implies all other (more specific) --with-foo options below.

    --with-osl
        Try to install or build the OpenShadingLanguage libraries (and their dependencies).
        Still experimental!

    --with-opencollada
        Build and install the OpenCOLLADA libraries.

    --all-static
        Build libraries as statically as possible, to create static builds of Blender.

    --force-all
        Force the rebuild of all built libraries.

    --force-python
        Force the rebuild of Python.

    --force-numpy
        Force the rebuild of NumPy.

    --force-boost
        Force the rebuild of Boost.

    --force-ocio
        Force the rebuild of OpenColorIO.

    --force-oiio
        Force the rebuild of OpenImageIO.

    --force-llvm
        Force the rebuild of LLVM.

    --force-osl
        Force the rebuild of OpenShadingLanguage.

    --force-opencollada
        Force the rebuild of OpenCOLLADA.

    --force-ffmpeg
        Force the rebuild of FFMpeg.

    Note about the --force-foo options:
        * They obviously only have an effect if those libraries are built by this script
          (i.e. if there is no available and satisfactory package)!
        * If the “force-rebuilt” library is a dependency of others, it will force the rebuild
          of those libraries too (e.g. --force-boost will also rebuild oiio and osl...).
        * Do not forget --with-osl if you built it and still want it!

    --skip-python
        Unconditionally skip Python installation/building.

    --skip-numpy
        Unconditionally skip NumPy installation/building.

    --skip-boost
        Unconditionally skip Boost installation/building.

    --skip-ocio
        Unconditionally skip OpenColorIO installation/building.

    --skip-oiio
        Unconditionally skip OpenImageIO installation/building.

    --skip-llvm
        Unconditionally skip LLVM installation/building.

    --skip-osl
        Unconditionally skip OpenShadingLanguage installation/building.

    --skip-opencollada
        Unconditionally skip OpenCOLLADA installation/building.

    --skip-ffmpeg
