  13 Optional COMPONENTS
  14 ^^^^^^^^^^^^^^^^^^^
  15
  16 .. versionadded:: 3.24
  17
  18 This module respects several optional COMPONENTS.
  19 There are corresponding imported targets for each of these.
  20
  21 ``glslc``

  23
  24 ``glslangValidator``
  25   The ``glslangValidator`` tool.
  26
  27 ``glslang``
  28   The SPIR-V generator library.
  29
  30 ``shaderc_combined``
  31   The static library for Vulkan shader compilation.
  32
  33 ``SPIRV-Tools``
  34   Tools to process SPIR-V modules.
