DyninstLibrary
--------------

This module provides a uniform interface for creating a Dyninst
toolkit target.

  dyninst_library

  This command is a wrapper around `add_library` that creates a
  SHARED and, optionally, STATIC library for a Dyninst toolkit.

    dyninst_library(<TargetName>
      [PRIVATE_HEADER_FILES <file>...]
      [PUBLIC_HEADER_FILES <file>...]
      [SOURCE_FILES <file>...]
      [DEFINES <val>...]
      [DYNINST_DEPS <target>...]
      [PUBLIC_DEPS <target>...]
      [PRIVATE_DEPS <target>...]
    )

  The <TargetName>_TARGETS variable will contain the names of the
  created targets for this toolkit.

  The options are:

  PRIVATE_HEADER_FILES
    A list of header files that are needed to build <TargetName>, but
    are not part of the public interface. These files are not copied
    into the install tree.

  PUBLIC_HEADER_FILES
    A list of header files that are part of the toolkit's public API.
    These files are copied into the install tree.

  SOURCE_FILES
    A list of source files for building the library. They are always
    considered PRIVATE attributes of the target as in `target_sources`.

  DEFINES
    A list of compiler definitions to attach to the target. These are
    always PRIVATE attributes of the target.

  DYNINST_DEPS
    A list of dependent Dyninst targets. If a target for a static library
    is created, it will link against the corresponding static target for
    each library container here.

  PUBLIC_DEPS
    A list of targets that are PUBLIC dependencies of <TargetName>.

  PRIVATE_DEPS
    A list of targets that are PRIVATE dependencies of <TargetName>.
