+# This module defines :prop_tgt:`IMPORTED` target ``LIBM::LIBM``, if

+#
+# 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.
