It seems that it doesn't solve this problem.
The link command line for `arrow-flight-test` has
`googletest_ep-prefix/lib/libgmockd.so` but it's not linked to
`arrow-flight-test` directly. (`libgtestd.so` and `libgtest_maind.so` are
linked directly.)
```console
$ objdump -p build/cpp/debug/arrow-flight-test | grep NEEDED
NEEDED libarrow_flight_testing.so.1300
NEEDED libarrow_testing.so.1300
NEEDED libgtest_maind.so.1.11.0
NEEDED libarrow_flight.so.1300
NEEDED libgrpc.so.10
NEEDED libarrow.so.1300
NEEDED libgtestd.so.1.11.0
NEEDED libstdc++.so.6
NEEDED libgcc_s.so.1
NEEDED libc.so.6
NEEDED ld-linux-x86-64.so.2
```
`arrow-flight-test` has rpath to bundled GoogleTest:
```console
$ objdump -p build/cpp/debug/arrow-flight-test | grep RUNPATH
RUNPATH /build/cpp/debug:/build/cpp/googletest_ep-prefix/lib
```
So directed linked `libgtestd.so` and `libgtest_maind.so` can be found but
`libgmockd.so` can't:
```console
$ ldd build/cpp/debug/arrow-flight-test | grep libg
