Description
when building qtbase static:
/usr/bin/cmake -DFEATURE_developer_build=ON -DBUILD_SHARED_LIBS=OFF -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=/usr/bin/gcc-10 -DCMAKE_CXX_COMPILER=/usr/bin/g++-10 -G Ninja -DCMAKE_CXX_FLAGS=-Wfatal-errors /home/andreasbuhr/development/qtdev/qtbase 2>&1 | tee buildlog.txt
it fails to build with errors like

The reason is that the order in the linker command line is wrong:
On the command line,
src/corelib/CMakeFiles/Core_resources_1.dir/./.rcc/qrc_mimetypes.cpp.o
appears after
lib/libQt6Core.a
. This cannot work, as qrc_mimetypes relies on libQt6Core.a. Changing the linker command line manually from
/usr/bin/g++-10 -Wfatal-errors -g -Wl,--gc-sections -Wl,--enable-new-dtags tests/auto/corelib/io/qprocess/testProcessEcho2/CMakeFiles/testProcessEcho2.dir/testProcessEcho2_autogen/mocs_compilation.cpp.o tests/auto/corelib/io/qprocess/testProcessEcho2/CMakeFiles/testProcessEcho2.dir/main.cpp.o -o tests/auto/corelib/io/qprocess/testProcessEcho2/testProcessEcho2 lib/libQt6Core.a lib/libQt6Core_qobject.a -lpthread /usr/lib/x86_64-linux-gnu/libz.so /usr/lib/x86_64-linux-gnu/libdouble-conversion.so -lm /usr/lib/x86_64-linux-gnu/libicui18n.so /usr/lib/x86_64-linux-gnu/libicuuc.so /usr/lib/x86_64-linux-gnu/libicudata.so /usr/lib/x86_64-linux-gnu/libpcre2-16.so -ldl /usr/lib/x86_64-linux-gnu/libglib-2.0.so /usr/lib/x86_64-linux-gnu/libgthread-2.0.so /usr/lib/x86_64-linux-gnu/librt.so src/corelib/CMakeFiles/Core_resources_1.dir/./.rcc/qrc_mimetypes.cpp.o
to

solves the problem. But one cannot fix each linker command manually.
