dub not building mir-glas with dependencies

[jmh530]

I'm on Windows 7 64bit with dmd 2.74.0, ldc 1.3.0 beta2, dub 1.3.0, and Visual Studio 2017.

The dub header to the mir-glas readme.md suggests that one can include a mir-glas project in a dub project essentially automatically. However, I have not had much success with this.

I created a new dub project with the following dub.json

{
    "name": "testing_mir_glas",
    "authors": [
        "jmh530"
    ],
    "dependencies": {
        "mir-algorithm": ">=0.6.6",
        "mir-glas": ">=0.2.3",
        "mir-cpuid": ">=0.5.2"
    },
    "dflags-ldc2": ["-mcpu=native"],
    "lflags": ["-L$MIR_GLAS_PACKAGE_DIR", "-L$MIR_CPUID_PACKAGE_DIR"],
    "description": "A minimal D application.",
    "license": "proprietary"
}

and source\app.d (was going to add mir-glas stuff later)

import std.stdio;
import mir.ndslice.algorithm : sliced;

void main()
{
    auto x = [1, 2, 3, 4, 5].sliced;
    writeln("done.");
}

I tried compiling with dub build, dub build --compiler=ldmd2, and dub build --compiler=ldc2. The result is basically the same

C:\ProgrammingFiles\DFiles\testing\testing_mir_glas>dub build --compiler=ldmd2
The determined compiler type "ldc" doesn't match the expected type "dmd". This w
ill probably result in build errors.

@jmh530 did you manage to compile the program?

[jmh530]

@MigMuc I have not tried again recently on this machine.

I'm having the same problem (Windows 7 64bit, dmd v2.76.0, ldc v1.5.0 beta1)

Running pre-build commands...
The determined compiler type "ldc" doesn't match the expected type "dmd". This will probably result in build errors.
Neither a package description file, nor source/app.d was found in

It looks like $MIR_GLAS_PACKAGE_DIR is appended to the project directory, which obviously results in a non existing path.
