Wes McKinney commented on ARROW-12626:
--------------------------------------
[~assignUser] the C++ build system does not support system / toolchain xsimd at
all, which you can see in this code:
{code}
if(ARROW_USE_XSIMD)
set(xsimd_SOURCE "BUNDLED")
resolve_dependency(xsimd)
add_library(xsimd INTERFACE IMPORTED)
if(CMAKE_VERSION VERSION_LESS 3.11)
set_target_properties(xsimd PROPERTIES INTERFACE_INCLUDE_DIRECTORIES
"${XSIMD_INCLUDE_DIR}")
else()
target_include_directories(xsimd INTERFACE "${XSIMD_INCLUDE_DIR}")
endif()
endif()
{code}
It would be good to support the user's toolchain xsimd (for example: installed
by conda) if it is new enough
> [C++] Build doesn't find external xsimd, and then installs a bundled one into
> a wrong path
