Blender Convenience Targets
   Provided for building Blender, (multiple at once can be used).

   * debug:         Build a debug binary.
   * full:          Enable all supported dependencies & options.
   * lite:          Disable non essential features for a smaller binary and faster build.
   * release:       Complete build with all options enabled including CUDA and Optix, matching the releases on blender.org
   * headless:      Build without an interface (renderfarm or server automation).
   * cycles:        Build Cycles standalone only, without Blender.
   * bpy:           Build as a python module which can be loaded from python directly.
   * developer:     Enable faster builds, error checking and tests, recommended for developers.
   * ninja:         Use ninja build tool for faster builds.
   * ccache:        Use ccache for faster rebuilds.

   Note: passing the argument 'BUILD_DIR=path' when calling make will override the default build dir.
   Note: passing the argument 'BUILD_CMAKE_ARGS=args' lets you add cmake arguments.

Other Convenience Targets
   Provided for other building operations.

   * config:        Run cmake configuration tool to set build options.
   * deps:          Build library dependencies (intended only for platform maintainers).

                    The existance of locally build dependancies overrides the pre-built dependencies from subversion.
                    These must be manually removed from '../lib/' to go back to using the pre-compiled libraries.

Project Files
   Generate project files for development environments.

   * project_qtcreator:     QtCreator Project Files.
   * project_netbeans:      NetBeans Project Files.
   * project_eclipse:       Eclipse CDT4 Project Files.

Package Targets

   * package_debian:    Build a debian package.
   * package_pacman:    Build an arch linux pacman package.
   * package_archive:	Build an archive package.

Testing Targets
   Not associated with building Blender.

   * test:
     Run automated tests with ctest.
   * test_cmake:
     Runs our own cmake file checker
     which detects errors in the cmake file list definitions
   * test_pep8:
     Checks all python script are pep8
     which are tagged to use the stricter formatting
   * test_deprecated:
     Checks for deprecation tags in our code which may need to be removed

Static Source Code Checking
   Not associated with building Blender.

   * check_cppcheck:        Run blender source through cppcheck (C & C++).
   * check_clang_array:     Run blender source through clang array checking script (C & C++).
   * check_splint:          Run blenders source through splint (C only).
   * check_sparse:          Run blenders source through sparse (C only).
   * check_smatch:          Run blenders source through smatch (C only).
   * check_descriptions:    Check for duplicate/invalid descriptions.

Spell Checkers
   This runs the spell checker from the developer tools repositor.

   * check_spelling_c:      Check for spelling errors (C/C++ only),
   * check_spelling_osl:    Check for spelling errors (OSL only).
   * check_spelling_py:     Check for spelling errors (Python only).

   Note: an additional word-list is maintained at: 'source/tools/check_source/check_spelling_c_config.py'

   Note: that spell checkers can take a 'CHECK_SPELLING_CACHE' filepath argument,
   so re-running does not need to re-check unchanged files.

   Example:
      make check_spelling_c CHECK_SPELLING_CACHE=../spelling_cache.data

Utilities
   Not associated with building Blender.

   * icons:
     Updates PNG icons from SVG files.

     Optionally pass in variables: 'BLENDER_BIN', 'INKSCAPE_BIN'
     otherwise default paths are used.

     Example
        make icons INKSCAPE_BIN=/path/to/inkscape

   * icons_geom:
     Updates Geometry icons from BLEND file.

     Optionally pass in variable: 'BLENDER_BIN'
     otherwise default paths are used.

     Example
        make icons_geom BLENDER_BIN=/path/to/blender

   * source_archive:
     Create a compressed archive of the source code.

   * update:
     updates git and all submodules

   * format:
     Format source code using clang (uses PATHS if passed in). For example::

        make format PATHS="source/blender/blenlib source/blender/blenkernel"

Environment Variables

   * BUILD_CMAKE_ARGS:      Arguments passed to CMake.
   * BUILD_DIR:             Override default build path.
   * PYTHON:                Use this for the Python command (used for checking tools).
   * NPROCS:                Number of processes to use building (auto-detect when omitted).

Documentation Targets
   Not associated with building Blender.

   * doc_py:        Generate sphinx python api docs.
   * doc_doxy:      Generate doxygen C/C++ docs.
   * doc_dna:       Generate blender file format reference.
   * doc_man:       Generate manpage.

Information

   * help:              This help message.
   * help_features:     Show a list of optional features when building.
