The new file is present:
find /opt/android/ -name new
/opt/android/ndk/18.1.5063045/sources/cxx-stl/system/include/new
/opt/android/ndk/18.1.5063045/sources/cxx-stl/llvm-libc++/include/new
/opt/android/ndk/18.1.5063045/toolchains/llvm/prebuilt/linux-x86_64/lib64/clang/7.0.2/include/cuda_wrappers/new
I now discovered that at some point in testing using docker I forgot
to init and update the git submodules. I do that now and still have a
similar error.
I updated the https://github.com/kilx/gcompris-docker/blob/main/Dockerfile
When running cmake it reports:

Note the:

However it is present in gcompris/external.
Also, is the following warning important? cmake is version 3.18.4 but
I don't have the kf5doc* files anywhere.

After running cmake the ./qml_box2d-prefix/src/qml_box2d-build
directory is empty.
After running make with the following output the Makefile is created though.

However what you mention is not present in that file:
grep -Ei 'CXX|llvm|include' ./qml_box2d-prefix/src/qml_box2d-build/Makefile
(no result)
