## Problem summary Using object file-based chain-PCH instead of cmake’s target_precompile_headers. The internal header files of doris can also be added to the PCH, and the scope of files to be recompiled can be minimized when these header files are modified. But this will bring some problems: 1. Since ccache’s cache optimization for PCH files is based on the check of the file name suffix, and the suffix of the PCH files generated by this method is .o, there may be some ccache’s direct_cache_miss problems. -- This is an automated message from the Apache Git Service.
