Uwe L. Korn commented on PARQUET-871:
-------------------------------------
Two possible solutions:
* We introduce a second CMAKE_PARQUET_CXX_FLAGS that is only given to
{{parquet-cpp}} sources.
* We blacklist various options that shouldn't be passed to third-party
components, e.g {{-Werror}}
The passing of CXXFLAGS to the thirdparty sources is essential for debugging
and release flag purposes. Also I need this for the clang-sanitizers.
> [C++] Mechanism to avoid passing -Werror to thirdparty libraries

> URL: https://issues.apache.org/jira/browse/PARQUET-871
> Project: Parquet
> Issue Type: Bug
> Components: parquet-cpp
> Reporter: Wes McKinney
>
> [~xhochy] I noticed after PARQUET-865 that my builds fail because I pass
> {{-Werror}} in {{$CXXFLAGS}}. I have
> {code}
> export CXXFLAGS="-Werror -Wall -fno-omit-frame-pointer"
> {code}
> How do we pass compiler flags to parquet-cpp only and not also the thirdparty
> libraries?
