# Options:
#   abi=N               build for compatibility with version N of the
#                       OpenVDB Grid ABI, where N is 2, 3, 4, etc.
#                       (some newer features will be disabled)
#   shared=no           link executables against static OpenVDB libraries
#                       (default: link against shared libraries)
#   debug=yes           build with debugging symbols and without optimization
#   verbose=yes         run commands (e.g., doxygen) in verbose mode


#
# The following variables must be defined, either here or on the command line
# (e.g., "make install DESTDIR=/usr/local"):
#
# Note that if you plan to build the Houdini OpenVDB tools (distributed
# separately), you must build the OpenVDB library and the Houdini tools
# against compatible versions of the Boost, OpenEXR and TBB libraries.
# Until Houdini 16.5, all three were included in the HDK, so the relevant
# variables below point by default to the HDK library and header directories:
# $(HDSO) and $(HT)/include, respectively.  (Source the houdini_setup script
# to set those two environment variables.)  Beginning with Houdini 16.5,
# you must provide your own distribution of Boost.
#
# To build the OpenVDB Python module, you will need local distributions of
# Python, Boost.Python, and optionally NumPy.  The Houdini HDK includes
# Python 2.x, but not the libboost_python library or NumPy or, as of
# Houdini 16.5, the Boost.Python headers, so both Boost.Python and NumPy
# have to be built separately.  Point the variables $(BOOST_PYTHON_LIB_DIR),
# $(BOOST_PYTHON_LIB) and $(NUMPY_INCL_DIR) below to your local distributions
# of those libraries.
