Building multiple WinRT executables with custom appxmanifests in one cmake script fails

Building a project that builds multiple UWP executables with all having a custom manifest fails.

Consider this cmake project that creates multiple executables, all having custom app manifests.
Configuring and building the project on the console fails because the image assets could not be found.

> cmake -S . -B build -DCMAKE_SYSTEM_NAME=WindowsStore -DCMAKE_SYSTEM_VERSION=10.0.0 -Dnumber_targets=2
...
> cmake --build build
...

When I remove the build folder, reconfigure and open the project in Visual Studio,
I can build the targets only once.

> rd /s /q build
> cmake -S . -B build -DCMAKE_SYSTEM_NAME=WindowsStore -DCMAKE_SYSTEM_VERSION=10.0.0 -Dnumber_targets=2
...
> cmake --open build
  1. Build target0 first: this should succeed.
    1. Rightclick on target0
    2. Click on Build
  2. Then, build target1: this succeeds as well.
    1. Rightclick on target 1
    2. Click on Build
  3. Build target0 again: this fails!
    1. Rightclick on target0
    2. Click on Build

The output window shows a message that suggests target0.appxmanifest references target1.exe, which it does not.

Build started...

Am I doing something wrong?

I apparently screwed up embedded images that caused the build to fail.
After fixing the image sizes, the issue of not being able to rebuild the executables remain.
I will open a new thread for this as the reproducer has become much easier.
