build ninja producing nonsense

[wbovela]

I have a simple CC65 project and VS64 2.6.1 with two source files sprites.s and sprites.c

The build.ninja file keeps generating this line:

build h$:\dev\cc65\projects\Sprites\build\sprites.o: asm h:\dev\cc65\projects\Sprites\sprites.sh:\dev\cc65\projects\Sprites\build\sprites.s

in which the assembly file name is repeated and the h:\ drive designation misses the $ sign (h$:)

And during the build there is this error:
ninja: error: h:\dev\cc65\projects\Sprites\build\build.ninja:53: expected newline, got ':'
build h$:\dev\cc65\projects\Sprites\build\sprites.o: asm h:\dev\cc65\pro...
^ near here

Where the "^ near here" points to the colon in the "asm h:" string.

These are my compile_commands.json:
[
{
"directory": "h:/dev/cc65/projects/Sprites",
"file": "h:/dev/cc65/projects/Sprites/sprites.c",
"arguments": [
"H:/dev/cc65/bin/cc65.exe",
"-DDEBUG",
"-D__cc65__",
"-D__fastcall__=/**/",
"-D__C64__",
"-Ih:/dev/cc65/projects/Sprites",
"-IH:/dev/cc65/include",
"-IH:/dev/cc65/include"
]
}
]

This is my project-config.json:
{
"name": "Sprites",
"description": "Project Sprites",
"toolkit": "cc65",
"sources": [
"sprites.c",
"sprites.s"
],
"build": "debug",
"definitions": [],
"includes": [],
"args": [],
"compiler": "",
"linkerFlags": [
"-m",
"sprites.map"
]
}

I have recreated the CC65 project with the VS Code command pallette, but the result is the same.

I think where this goes wrong is the following. Additional to everything I have a Makefile which I have used to compare results. This writes assembly output to the folder's root, instead of in the ./src folder.

It seems like everything works fine when I use the VS64 Create Project command from an empty folder, before I put any code in the folder (I thought it would be fine to do so). When I start in an empty folder and then add source files to the ./src folder alone, everything seems fine.

Perhaps add something about this to the instructions.
