  35 #
  36 # Using this source tree directly from a CMake-based project:
  37 #   1. Add an add_subdirectory directive to include this sub directory.
  38 #   2. Use ${SPIRV-Headers_SOURCE_DIR}/include} in a target_include_directories
  39 #      command.
  40 #
  41 # Installing the headers first, then using them with an implicit include
  42 # directory.  To install the headers:
  43 #   1. mkdir build ; cd build
  44 #   2. cmake ..
  45 #   3. cmake --build . --target install
