      I configure qtbase with

      ../configure -cmake -debug -xcb -no-warnings-are-errors -no-pch \
    -nomake tests -nomake examples \
    -prefix /home/cc-runs/install_dir \
    -no-sse3 -no-ssse3 -no-sse4.1 -no-sse4.2 -no-avx -no-avx2 -no-avx512 \
    -- -DCMAKE_C_COMPILER=clang-11 -DCMAKE_CXX_COMPILER=clang++-11 -DCMAKE_CXX_FLAGS=-stdlib=libc++

      Then I was getting strange linking errors ("symbol not found") in QtSvg module. I configure QtSvg as:

      /home/cc-runs/install_dir/bin/qt-configure-module ..

      My linking errors were gone after changing the configure line as such:

      /home/cc-runs/install_dir/bin/qt-configure-module .. -- -DCMAKE_CXX_FLAGS='-stdlib=libc++'

      Shouldn't the CMAKE_CXX_FLAGS be remembered? Please note that CMAKE_CXX_COMPILER is indeed remembered.
