# FindLibM
# --------
#
# Find the native realtime includes and library.
#
# IMPORTED Targets
# ^^^^^^^^^^^^^^^^
#
# This module defines :prop_tgt:`IMPORTED` target ``LIBM::LIBM``, if
# LIBM has been found.
#
# Result Variables
# ^^^^^^^^^^^^^^^^
#
# This module defines the following variables:
#
# ::
#
# LIBM_INCLUDE_DIRS - where to find math.h, etc.
# LIBM_LIBRARIES - List of libraries when using libm.
# LIBM_FOUND - True if math library found.
#
# Hints
# ^^^^^
#
# A user may set ``LIBM_ROOT`` to a math library installation root to tell this
# module where to look.
