Title:
  imagemagick should be built with WebP support

Status in imagemagick package in Ubuntu:
  Confirmed

Bug description:
  Background discussion:

  http://askubuntu.com/questions/251950/imagemagick-convert-cant-
  convert-to-webp

  The very simple fix is to have the Ubuntu build scripts changed to
  enable WebP support per the comments:

  """
  The Ubuntu source package for imagemagick does not declare a build dependency on libwebp-dev. Thus imagemagick gets built without webp support. This could be considered a bug in Ubuntu.

  Relevant output from the build process:

  checking for WEBP... 
  checking webp/decode.h usability... no
  checking webp/decode.h presence... no
  checking for webp/decode.h... no
  checking for WebPDecodeRGB in -lwebp... no
  checking if WEBP package is complete... no

  And when libwebp-dev Install libwebp-dev is installed:

  checking for WEBP... 
  checking webp/decode.h usability... yes
  checking webp/decode.h presence... yes
  checking for webp/decode.h... yes
  checking for WebPDecodeRGB in -lwebp... yes
  checking if WEBP package is complete... yes

  If you want to fix this just for yourself, you can rebuild the package
  and install your version:

  cd /tmp
  mkdir imagemagick
  cd imagemagick
  sudo apt-get build-dep imagemagick
  sudo apt-get install libwebp-dev devscripts
  apt-get source imagemagick
  cd imagemagick-*
  debuild -uc -us
  sudo dpkg -i ../*magick*.deb
