Xcode: Unable to code sign when embeding a macOS framework inside two different bundles

I have project where I create a macOS framework and then embed the framework inside two different executable/bundles with code signing enabled. Configuring and generating is working with command cmake -G Xcode ... But when I build the project with cmake --build . --config Debug it's failing with error:

/usr/bin/codesign --force --sign XXXXXXXXXXXXXXXXX -o runtime --entitlements /Users/jcarl/devel/CMake_Embed_Sign_Framework/build/exe1/EmbedFrameworkTwice.build/Debug/exe1.build/Exe1.app.xcent --timestamp\=none /Users/jcarl/devel/CMake_Embed_

Command CodeSign failed with a nonzero exit code

It's randomly failing with one of my bundles.

I attached a project where you can reproduce the error. NOTE: A Apple Development Team ID has to be set in the main CMakeLists.txt.

I also dug a little bit into the generated Xcode project file to understand what maybe going wrong. In the section PBXBuildFile I see the framework

3686758ACF9F40438DA851F4 = {isa = PBXBuildFile; fileRef = 7B19B44200274907B37896E8 /* fwk */; settings = {ATTRIBUTES = (RemoveHeadersOnCopy,CodeSignOnCopy); }; };

which then referenced twice in the section PBXCopyFilesBuildPhase

926C40A995274995A5E04088 /* Embed Frameworks */ = {
    isa = PBXCopyFilesBuildPhase;
    buildActionMask = 2147483647;
    dstPath = "";
    dstSubfolderSpec = 10;
    files = (
        3686758ACF9F40438DA851F4,
    );
    name = "Embed Frameworks";
    runOnlyForDeploymentPostprocessing = 0;
};
F06C43EF489147F8BA027FC0 /* Embed Frameworks */ = {
    isa = PBXCopyFilesBuildPhase;
    buildActionMask = 2147483647;
    dstPath = "";
    dstSubfolderSpec = 10;
    files = (
        3686758ACF9F40438DA851F4,
    );
    name = "Embed Frameworks";
    runOnlyForDeploymentPostprocessing = 0;
};

From my limited understand of Xcode it seems that Xcode gets upset if a PBXBuildFile referenced by two different PBXCopyFilesBuildPhase.
