# This file introduces a template for calling write_cmake_config.py.
|
|
#
|
|
# write_cmake_config behaves like CMake's configure_file(), but runs at build
|
|
# time, not at generator time. See write_cmake_config.py for details.
|
|
#
|
|
# Parameters:
|
|
#
|
|
# input (required) [string]
|
|
#
|
|
# output (required) [string]
|
|
#
|
|
# values (required) [list of strings]
|
|
# Each entry is a '='-separated key-value pair used for substitution.
|
|
#
|
|
# Example use:
|
|
#
|
|
# write_cmake_config("attributes_compat_func_gen") {
|
|
# input = "Version.inc.in"
|
|
# output = "$root_gen_dir/clang/include/clang/Basic/Version.inc",
|
|
# values = [
|
|
# "CLANG_VERSION=$llvm_version",
|
|
# ]
|
|
# }
|
|
|
