# clang_tablegen output-file [tablegen-arg ...] SOURCE source-file
# [[TARGET cmake-target-name] [DEPENDS extra-dependency ...]]
#
# Generates a custom command for invoking tblgen as
#
# tblgen source-file -o=output-file tablegen-arg ...
#
# and, if cmake-target-name is provided, creates a custom target for
# executing the custom command depending on output-file. It is
# possible to list more files to depend after DEPENDS.
