# Functions used by BUILD.cmake files
# The CMake build handles the target kinds in different ways:
# 'cmd'       - Translates to a CMake executable target.
# 'lib'       - Translates to CMake static library.
#               If TINT_BUILD_FUZZERS is enabled, then a second static library with
#               the ${TINT_FUZZ_SUFFIX} suffix is also created. This is done because
#               the fuzzer build requires compilation with the '-fsanitize=fuzzer'
#               flag, which results in a separate set of compilation units.
# 'test'      - Translates to a CMake object library, configured for compiling and
#               linking against google-test.
# 'bench'     - Translates to a CMake object library, configured for compiling and
#               linking against google-benchmark.
# 'test_cmd'  - Translates to a CMake executable target linked against google-test.
# 'bench_cmd' - Translates to a CMake executable target linked against google-benchmark.
