Sphinx suppress specific warnings?

Question

In building my documentation I'm running into a lot of warning messages such as the following:

/home/X/Y/src/core/include/math/bigintntl/transformntl.h:92: warning: documented empty return type of NTL::NumberTheoreticTransformNtl::ForwardTransformToBitReverseInPlace. I'd like to turn off the specific warnings related to X is not documented. How might I go about doing so? I'm building the documentation of a rather large library, and until we have time to go back and update the docs, this just adds a lot of noise to our builds.

The documenting line:

  /**
   * In-place forward transform in the ring Z_q[X]/(X^n+1) with prime q and
   * power-of-two n s.t. 2n|q-1. Bit reversing indexes. [Algorithm 1 in
   * https://eprint.iacr.org/2016/504.pdf]
   *
   * @param &rootOfUnityTable is the table with the n-th root of unity powers in
   * bit reverse order.
   * @param &element[in,out] is the input/output of the transform of type VecType and length n.
   * @return none
   */
  void ForwardTransformToBitReverseInPlace(
      const VecType& rootOfUnityTable, VecType* element);

from OpenFHE library

and the .rst file looks like the following (autodoxygenindex is a Breathe directive: https://breathe.readthedocs.io/en/latest/directives.html#autodoxygenindex):

Core Math Big Int NTL Documentation

.. autodoxygenindex::
   :project: core_math_bigintntl

while the conf.py file is here.

Looks like the issue for me was that breathe was regenerating the documentation because I was using a specific command. Unfortunately, this regeneration seemed to ignore the Doxyfile that was coming in. So, I had to manually pass in the relevant variables via breathe_doxygen_config_options See breathe config-values
