# 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.
