maybe add "(@id:asabil.meson)" because there is another extension
called meson.

But first we need the ms-vscode.cpptools extension.

Not sure about +build... This produces:

When opening .json I get many:

"false" is not defined (Pylance reportUndefinedVariable)

I got these warnings:
[5/12/2021, 12:24:04 PM]
"${workspaceFolder}/builddir/compile_commands.json" could not be found.
'includePath' from c_cpp_properties.json in folder 'qemu' will be used
instead.
[5/12/2021, 12:24:04 PM] For C source files, IntelliSenseMode was
changed from "linux-gcc-x64" to "linux-clang-x64" based on compiler args
and querying compilerPath: "/usr/lib64/ccache/clang"
[5/12/2021, 12:24:04 PM] For C++ source files, IntelliSenseMode was
changed from "linux-gcc-x64" to "linux-clang-x64" based on compiler args
and querying compilerPath: "/usr/lib64/ccache/clang"
Then when pressing Ctrl+Shift+B to run the build task:
> Executing task: C/C++: build active file with compile_commands.json <
Starting build...
python3 /home/phil/source/qemu/scripts/rebuild.py
/home/phil/source/qemu/builddir/meson-info/meson-info.json
Traceback (most recent call last):
File "/home/phil/source/qemu/scripts/rebuild.py", line 14, in <module>
with open('compile_commands.json') as f:
FileNotFoundError: [Errno 2] No such file or directory:
'compile_commands.json'
Build finished with error(s).
The terminal process failed to launch (exit code: -1).
I don't see any target in the Meson view.
BTW I also installed the 'ms-python.python' extension and
got 'ms-azuretools.vscode-docker' suggested.

Phil.
