Kouhei Sutou commented on ARROW-16993:
--------------------------------------
Thanks.
{noformat}
-- Could NOT find Boost: missing: system filesystem (found
/usr/local/lib/cmake/Boost-1.76.0/BoostConfig.cmake (found suitable version
"1.76.0", minimum required is "1.58"))
{noformat}
is the root cause. You have system Boost but it doesn't include system and
filesystem components. So {{Boost::headers}} is loaded but system Boost
detection is failed. If system Boost detection is failed, we use bundled Boost
and create {{Boost::headers}} for bundled Boost but {{Boost::headers}} already
exists. It causes this error.
CMake doesn't provide a feature to remove a created target
({{Boost::headers}}). We may be able to support this case by reusing
(overriding) {{Boost::headers}} defined by system Boost but it may not be a
good CMake manner...
I think that installing Boost's system and filesystem components to your system
is the best solution for this case for now.
