# This file introduces a templates 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",
# ]
# }
template("write_cmake_config") {
assert(defined(invoker.input), "must set 'input' in $target_name")
assert(defined(invoker.output), "must set 'output' in $target_name")
assert(defined(invoker.values), "must set 'values' in $target_name")
action(target_name) {
script = "//llvm/utils/gn/build/write_cmake_config.py"
sources = [
invoker.input,
]
outputs = [
invoker.output,
]
args = [
"-o",
rebase_path(outputs[0], root_build_dir),
rebase_path(sources[0], root_build_dir),
] + invoker.values
forward_variables_from(invoker,
[
"configs",
"deps",
"public_configs",
"public_deps",
"visibility",
])
}
