Above is your clue. Your build could not run `configure`. Your problem
is most likely in

```
ExternalProject_Add(project_libsndfile
    GIT_REPOSITORY     https://github.com/erikd/libsndfile.git
    PREFIX              lib/libsndfile
    CONFIGURE_COMMAND   <SOURCE_DIR>/configure
    BUILD_COMMAND       make
    BUILD_IN_SOURCE     1
    INSTALL_COMMAND     echo Skipping install step for libsndfile
)
```

Running a `configure` script is not going to work on Windows out of
the box because libsnd uses GNU autotools which is for made for UNIX
like operating systems. You should try and figure out how (if it's
even possible) to build libsnd on Windows. At glance at the GitHub
page shows they have a CMake build system but the docs say it will
likely only work on Linux. There are some commits that mention MINGW
so maybe it might be possible to build using the MSYS environment.

Good Luck.
