Fixed ld error and override warning when compiling xbcloud-t. (when using the -DWITH_UNIT_TESTS:BOOL=TRUE cmake flag)

How to reproduce

Used CMake flags

CMAKE_SRC_CONFIGURE_PARAMS=(
    -DBUILD_CONFIG:STRING=xtrabackup_release
    -DINSTALL_LAYOUT:STRING="RPM"  
    -DENABLED_PROFILING:BOOL=TRUE
    -DENABLE_GCOV:BOOL=FALSE
    -DENABLE_GPROF:BOOL=FALSE
    -DENABLED_LOCAL_INFILE:BOOL=TRUE
    -DWITH_ASAN:BOOL=FALSE
    -DWITH_EXTRA_CHARSETS:STRING=all
    -DWITH_EDITLINE:STRING=system
    -DWITH_UNIT_TESTS:BOOL=TRUE
    -DWITH_VALGRIND:BOOL=FALSE
    -DWITH_ZLIB:STRING=system
    -DWITH_SSL:STRING=system
    -DWITH_CLIENT_PROTOCOL_TRACING:BOOL=FALSE
    -DWITH_LZ4:STRING=system
    -DWITH_MSAN:BOOL=FALSE
    -DWITH_PROTOBUF:STRING=bundled
    -DWITH_TEST_TRACE_PLUGIN:BOOL=FALSE
    -DWITH_UBSAN:BOOL=FALSE
    -DWITH_XTRABACKUP:BOOL=TRUE
    -DWITH_FIDO=system
    -DWITH_ICU=system
    -DWITH_RAPIDJSON:STRING=bundled
    -DWITH_MAN_PAGES=OFF
)

Configure

cmake -B build ${CMAKE_SRC_CONFIGURE_PARAMS[@]}

Compile

cmake --build build -j$(nproc)

Install (optional)

cmake --install build

Results

The warning appears at 26% of the compilation:

And the error at 27% of the compilation:

Notes

• The issues are in the trunk, 8.4 and 8.0 branches, so they need to be fixed on those three branches.
• I tested on a clean machine (not graphical) with just the requested dependencies, as specified in the tutorial.

Also... I'm wondering, how I can run the unit tests after compilation?
