    Description

      I am trying to build qtwebengine.

      I did 

      /usr/bin/cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=/usr/bin/gcc-11 -DCMAKE_CXX_COMPILER=/usr/bin/g++-11 -G Ninja -DCMAKE_CXX_FLAGS=-Wfatal-errors -DCMAKE_TOOLCHAIN_FILE=/home/andreasbuhr/development/qtdev/qtbase/cmake-build-debug/lib/cmake/Qt6/qt.toolchain.cmake /home/andreasbuhr/development/qtdev/qtwebengine

      and then

      cmake --build . --parallel 1

      But my 64GB RAM system starts swapping very quickly. The "parallel 1" setting is ignored, it spins of 24 compilers and runs out of RAM.
