# There are two ways to use this project.
#
# Using this source tree directly from a CMake-based project:
#   1. Add an add_subdirectory directive to include this sub directory.
#   2. Use ${SPIRV-Headers_SOURCE_DIR}/include} in a target_include_directories
#      command.
#
# Installing the headers first, then using them with an implicit include
# directory.  To install the headers:
#   1. mkdir build ; cd build
#   2. cmake ..
#   3. cmake --build . --target install
