# ~~~
# NEURON module installation:
# - OFF : do not install
# - ON : install in ${CMAKE_INSTALL_PREFIX} (default)
# NOTE: When building the wheel, this is set to OFF.
# Dynamic Python version support:
# - NRN_ENABLE_PYTHON_DYNAMIC=OFF : libnrniv is linked against a single Python version, which
# can be steered with PYTHON_EXECUTABLE
# - NRN_ENABLE_PYTHON_DYNAMIC=ON : libnrniv is not linked against Python, distinct libnrnpython
# libraries are built for each configured Python major.minor
# version but are only linked against the relevant libpython
# if NRN_LINK_AGAINST_PYTHON is true, which is by default only
# the case on windows.
# nrniv/special still works in the absence of Python, and
# dynamically loads the appropriate libnrnpythonX.Y as needed
# - NRN_PYTHON_DYNAMIC=pythonX;... : semicolon separated list of Python versions used when
# NRN_ENABLE_PYTHON_DYNAMIC=ON, if not set then it defaults to
# PYTHON_EXECUTABLE. This must include all major.minor
# versions that you want nrniv -python to be able to load. If
# this *is* set then the first entry will be used as the
# default Python version.
# Extra options for extended Python tests:
# - NRN_PYTHON_EXTRA_FOR_TESTS=... : semicolon separated list of Python executables that NEURON
# is *not* built against. These are only used for testing, and
# there must be no overlap in major.minor versions between
# this list and the set of versions that NEURON *is* built
# against. This allows tests of failure modes.
# Dynamic MPI support:
# - OFF : nrnmpi is linked into libnrniv.so
# - ON : nrnmpi interface consistent with default mpi is built and loaded dynamically
# at run time (nrniv still works in the absence of any mpi at all).
# - <string> : semicolon (;) separated list of MPI's bin directories to create a separate
# libnrnmpi_xxx.so interface for each. When nrniv is launched with the -mpi argument,
