-----------------------------------
Assignee: Kouhei Sutou
> [C++] Headers of system Boost not found in non-standard location
> ----------------------------------------------------------------
>
> Key: ARROW-6421
> URL: https://issues.apache.org/jira/browse/ARROW-6421
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Reporter: Ingo Müller
> Assignee: Kouhei Sutou
> Priority: Minor
>
> On a system that does not have boost installed in a default location, but in
> a non-default one, the boost headers are not found during compilation. This
> is true even though CMake correctly finds the Boost installation, e.g.,
> through CMAKE_PREFIX_PATH.
> The problem is the function ADD_ARROW_LIB LIB_NAME in
> cpp/cmake_modules/BuildUtils.cmake, which defines a target
> "{$LIB_NAME]_objlib" without the required dependencies (without any
> dependencies, actually). The required _compile-time_ dependencies are
> specified as properties of the corresponding_"_targets", for example, of the
> Boost::filesystem target. They should be added as dependencies using
> target_link_libraries (even though the name suggests that this is only for
> _link-time_ dependencies).
> The following patch solves the problem, but might not be the best solution:
> {noformat}

> # export CMAKE_PREFIX_PATH=/opt/boost-1.70.0
> # Compile the cpp project without setting -DBOOST_SOURCE or similar. Make
> sure CMake found your Boost installation in /opt
