---------------------------------------
You probably mean "{{-Dc-ares_SOURCE=BUNDLED".}}
> [C++] Bundled gRPC fails building (cannot find c-ares)
> ------------------------------------------------------
>
> Key: ARROW-5192
> URL: https://issues.apache.org/jira/browse/ARROW-5192
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Reporter: Antoine Pitrou
> Assignee: Wes McKinney
> Priority: Major
>
> If I try to build Arrow C++ without a conda toolchain, I get the following
> error when gRPC is being built by the cmake files:
> {code}
> CMake Error at cmake/cares.cmake:38 (find_package):
> Could not find a package configuration file provided by "c-ares" with any
> of the following names:
> c-aresConfig.cmake
> c-ares-config.cmake
> Add the installation prefix of "c-ares" to CMAKE_PREFIX_PATH or set
> "c-ares_DIR" to a directory containing one of the above files. If "c-ares"
> provides a separate development package or SDK, be sure it has been
> installed.
> Call Stack (most recent call first):
> CMakeLists.txt:139 (include)
> {code}
> It seems c-ares is found by the following line in ThirdPartyToolchain.cmake:
> {code}
> find_package(c-aresAlt)
> {code}
> But gRPC doesn't pick it up...
