# Optional environment variables:
#
# To control where various third-party dependencies are.
# NOTE: If you change any of these partway through a build, you will need to
# clear out the build/ and install/ directories to be sure the proper build
# flags are used.

# * CONTRIB_DIR      : Dir with third-party dependencies (default: contrib)
# * MOOSE_DIR        : Top-level MOOSE dir (default: $(CONTRIB_DIR)/moose)
# * NEKRS_DIR        : Top-level NekRS dir (default: $(CONTRIB_DIR)/nekRS)
# * OPENMC_DIR       : Top-level OpenMC dir (default: $(CONTRIB_DIR)/openmc)
# * DAGMC_DIR        : Top-level DagMC dir (default: $(CONTRIB_DIR)/DAGMC)
# * MOAB_DIR         : Top-level Moab dir (default: $(CONTRIB_DIR)/moab)
# * GRIFFIN_DIR      : Top-level Griffin dir (default: $(CONTRIB_DIR)/griffin)
# * BISON_DIR        : Top-level Bison dir (default: $(CONTRIB_DIR)/bison)
# * SAM_DIR          : Top-level SAM dir (default: $(CONTRIB_DIR)/SAM)
# * SOCKEYE_DIR      : Top-level Sockeye dir (default: $(CONTRIB_DIR)/sockeye)

# * IAPWS95_DIR      : Top-level iapws95 dir (default: $(CONTRIB_DIR)/iapws95)

# * EIGEN3_DIR       : Top-level eigen3 dir (should contain FindEigen3.cmake). This
#                      is only needed if enabling DagMC.

# To control where OpenMC grabs HDF5 from; you don't need to set any of these unless
# you don't want to use the HDF5 that comes with PETSc

# * HDF5_ROOT         : Top-level HDF5 directory (default: $(PETSC_DIR)/$(PETSC_ARCH), meaning that
#                       the default is to use HDF5 downloaded by PETSc). This makefile
#                       will then get the header files from $(HDF5_ROOT)/include and the
#                       libraries from $(HDF5_ROOT)/lib.
# * HDF5_INCLUDE_DIR  : Top-level HDF5 header dir (default: $(HDF5_ROOT)/include)
# * HDF5_LIBDIR       : Top-level HDF5 lib dir (default: $(HDF5_ROOT)/lib)
# * PETSC_DIR         : Top-level PETSc dir (default: $(MOOSE_DIR)/petsc)
# * PETSC_ARCH        : PETSc architecture (default: arch-moose)
