Cairos's configure output: Is it enough for Firefox?

Question

I intend to compile Firefox from the source. For that, I do need to compile GTK. And for that, I do need to compile Cairo.

After solving some of Cairo's dependencies, I was able to run the configure script. Bellow, the result:

cairo (version 1.10.2 [release]) will be compiled with:

The following surface backends:
Image:         yes (always builtin)
Recording:     yes (always builtin)

The following font backends:

  FreeType:      no (freetype-config not found in path or $FREETYPE_CONFIG)
  Fontconfig:    no (freetype-config not found in path or $FREETYPE_CONFIG)
  Win32:         no (requires a Win32 platform)
  Quartz:        no (requires CoreGraphics framework)

The following functions:

   cairo-script-interpreter:   yes

And the following internal features:
  pthread:       yes
  gtk-doc:       no
  gcov support:  no
  symbol-lookup: no (requires bfd)
  test surfaces: no (disabled, use --enable-test-surfaces to enable)
  ps testing:    no (requires libspectre)
  pdf testing:   no (requires poppler-glib >= 0.13.3)
  svg testing:   no (requires librsvg-2.0 >= 2.15.0)


*** No native font backends enabled for your platform. It is strongly
*** recommended that you enable the native font backend feature for your
*** platform.

I am asking that mainly due to the warn above. Are those FreeType, FontType or Quartz really necessary (having Firefox in mind)? Anything else that would be nice to have? Thanks for the input.
