@rem Workaround: Windows NDK + spaces in project path
@rem
@rem ndk-build ultimately feeds paths into (GNU) make, which does not reliably
@rem handle spaces even when arguments are quoted. If the project path contains
@rem spaces, map it to a temporary drive letter with SUBST and run Gradle from
@rem there so all paths are space-free.
