# fgmeta layout, where windows-3rd-party is a sibling of our flightgear source dir

# - this should work with no manual options
|

# explicitly specifying MSVC_3RDPARTY_ROOT: we'll select a subdir based on MSVC version
|

# and architecture. We want to allow for people specify various paths here:
|

# - path to windows-3rd-party
|
||||
# - path to an MSVC versioned subdir, eg -DMSVC_3RDPARTY_ROOT=C:\FGFS\windows-3rd-party\msvc140
|
