* brew: udunits (OSX)
If udunits2 is already installed in a non-standard location, use:
--configure-args='--with-udunits2-lib=/usr/local/lib'
if the library was not found, and/or:
--configure-args='--with-udunits2-include=/usr/include/udunits2'
if the header was not found, replacing paths with appropriate values.
You can alternatively set UDUNITS2_INCLUDE and UDUNITS2_LIBS manually.
