Similar to the previous recipe, we need to configure a template file, but this time, we will emulate the configure_file() function with a Python script. We keep the CMakeLists.txt largely unchanged, but we replace configure_file(print_info.c.in print_info.c @ONLY) with a set of commands, which we will introduce step by step:
- First, we construct a variable, _config_script, which will hold a Python script that we will execute a moment later:
set(_config_script"from pathlib import Pathsource_dir = Path('${CMAKE_CURRENT_SOURCE_DIR}')binary_dir = Path('${CMAKE_CURRENT_BINARY_DIR}')input_file = source_dir / 'print_info.c.in'output_file = binary_dir / 'print_info.c'import syssys.path.insert(0, str(source_dir))from configurator import ...
