Function ExactExecutableFromAppBundle

vkconfig_core/executable.cpp:36–82

////////////////////////////////////////////////////////////////////// This is only used on macOS to extract the executable from the bundle. You have to look at the plist.info file, you can't just assume whatever you find in the /MacOS folder is the executable. The initial path is the folder where info.plist resides, and the path is completed to the executable upon completion. Note, not ALL macOS

/// executable is fed in here, it will silently just return without
/// modifying the path (which will be the correct behavior)
