 Using OpenDDS in a CMake Project

 OpenDDS can be used with `CMake <https://cmake.org>`__\-based projects by using the :ghfile:`OpenDDS CMake config package <cmake>`.
 This package bridges the gap between the MPC build system used by OpenDDS and CMake-based projects by providing :ref:`imported library targets <cmake-libraries>` and the ability to add IDL to a target using :cmake:func:`opendds_target_sources`.

 Config Variables

+They can be changed when configuring a :ref:`CMake-built OpenDDS <cmake-building>` using ``-D``, but should not be chagned after that.
