   7 To add the freeimage tool to the waf file:
   8 $ ./waf-light --tools=compat15,freeimage
   9         or, if you have waf >= 1.6.2
  10 $ ./waf update --files=freeimage
  11
  12 The wscript will look like:

  14 def options(opt):
  15         opt.load('compiler_cxx freeimage')
  16
  17 def configure(conf):
  18         conf.load('compiler_cxx freeimage')

  20         # you can call check_freeimage with some parameters.
  21         # It's optional on Linux, it's 'mandatory' on Windows if
  22         # you didn't use --fi-path on the command-line
  23
  24         # conf.check_freeimage(path='FreeImage/Dist', fip=True)
