Yes, it fails without it:

CMake Warning at CMakeLists.txt:32 (message):
  Couldn't find Qt4 or Qt5 -- will not build xpdf.

From the xpdf INSTALL file:
* Make sure you have the following installed:

    - CMake 2.8.8 or newer
    - FreeType 2.0.5 or newer
    - Qt 4.8.x or 5.x (for xpdf only)
    - libpng (for pdftoppm and pdftohtml)
    - zlib (for pdftoppm and pdftohtml)

  If Qt isn't found, the GUI viewer (xpdf) won't be built, but the
  command line tools will still be built.

This is also documented here:
http://www.xpdfreader.com/download.html

There may exist a cmake param to get the old bare xpdf, but
I've not found it.
