Static C++ libraries on Windows are known to be quite large. The Protocol Buffers static libraries on Windows are over 100MB. The size is not caused by thirdparty dependencies AFAIK, it's the result of object code produced by MSVC.
See https://github.com/conda-forge/libprotobuf-feedstock/issues/24 as an example On Linux these are the largest object code files and directories $ du -ab src/arrow/CMakeFiles/arrow_objlib.dir/ | sort -n -r | head -n 30 26091568 src/arrow/CMakeFiles/arrow_objlib.dir/ 13603208 src/arrow/CMakeFiles/arrow_objlib.dir/compute 13093888 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels 6471328 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/take.cc.o 3053736 src/arrow/CMakeFiles/arrow_objlib.dir/ipc 2688040 src/arrow/CMakeFiles/arrow_objlib.dir/array 1907720 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/filter.cc.o 1665648 src/arrow/CMakeFiles/arrow_objlib.dir/array/diff.cc.o 1621984 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/compare.cc.o 1172848 src/arrow/CMakeFiles/arrow_objlib.dir/json 991104 src/arrow/CMakeFiles/arrow_objlib.dir/ipc/json_simple.cc.o 874672 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/hash.cc.o 846608 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/cast.cc.o 828040 src/arrow/CMakeFiles/arrow_objlib.dir/ipc/json_internal.cc.o 779352 src/arrow/CMakeFiles/arrow_objlib.dir/builder.cc.o 702032 src/arrow/CMakeFiles/arrow_objlib.dir/csv 694520 src/arrow/CMakeFiles/arrow_objlib.dir/util 668528 src/arrow/CMakeFiles/arrow_objlib.dir/io 662600 src/arrow/CMakeFiles/arrow_objlib.dir/array.cc.o 509328 src/arrow/CMakeFiles/arrow_objlib.dir/json/converter.cc.o 475752 src/arrow/CMakeFiles/arrow_objlib.dir/array/builder_dict.cc.o 446872 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/isin.cc.o 434768 src/arrow/CMakeFiles/arrow_objlib.dir/type.cc.o 391720 src/arrow/CMakeFiles/arrow_objlib.dir/csv/converter.cc.o 363440 src/arrow/CMakeFiles/arrow_objlib.dir/pretty_print.cc.o 345496 src/arrow/CMakeFiles/arrow_objlib.dir/compute/expression.cc.o 337360 src/arrow/CMakeFiles/arrow_objlib.dir/json/parser.cc.o 334240 src/arrow/CMakeFiles/arrow_objlib.dir/compute/kernels/sort_to_indices.cc.o 324568 src/arrow/CMakeFiles/arrow_objlib.dir/ipc/writer.cc.o 315760 src/arrow/CMakeFiles/arrow_objlib.dir/ipc/reader.cc.o If you don't need any code in src/arrow/compute you can pass -DARROW_COMPUTE=OFF and probably trim the size of the static library a lot.
