141 # A dependency may optionally be followed by "OPTIONAL", which

144 # Dependencies prefixed with "os" represent the OS required to
145 # build the extension. The only valid value for this currently
146 # is osPosix, which represents everything with a valid posix
147 # API, which is most everything except for Windows.
149 # Dependencies prefixed with "var" represent a CMake variable
150 # which must evaluate to a trueish value for the extension to

154 # If there is a space in an argument with a string in it, and
