Build fails to find Qt4 on Ubuntu 16.04

[rdeits]

Hi Pat! I'm running into a strange build issue, and I was hoping you could help. I currently can't build Director on my Ubuntu 16.04 system. Running the superbuild cmake gives:

CMake Error at /home/rdeits/tools/cmake-3.5.2-Linux-x86_64/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find Qt4 (missing: QT_QTOPENGL_INCLUDE_DIR QT_QTOPENGL_LIBRARY)
  (found version "4.8.7")
Call Stack (most recent call first):
  /home/rdeits/tools/cmake-3.5.2-Linux-x86_64/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)

  /home/rdeits/locomotion/director/cmake/dd-macros.cmake:22 (find_package)
  cmake/externals.cmake:63 (setup_qt)
  CMakeLists.txt:27 (include)

I definitely have Qt4 installed (and have installed all of the apt packages from the Readme), but Director seems to be unhappy with that installation for some reason. We just tried building on Twan's computer (with 16.04) and it worked, so it's clearly something specific to my machine, but I don't even know where to begin. Any suggestions?

[rdeits]

Aha! It looks like I just needed libqt4-opengl-dev as well. I guess we should add that to the Readme.

hmm, I wonder why the deps in the Readme were not sufficient. Here is the dep install script that works for ubuntu 16 in docker, btw:

[rdeits]

Yeah, I'm also confused about that. Seems to be some artifact of the way my desktop is configured. Perhaps qt4-opengl was removed when I had to clean out the mesa-dev stuff that an old Drake version installed.

I ran into this as well while building inside a docker image. Installing libqt4-opengl-dev fixed the issue for me as well. For reference the director options I am setting are shown below.

cmake $director_src_dir/distro/superbuild \
      -DUSE_EXTERNAL_INSTALL:BOOL=ON \
      -DUSE_DRAKE:BOOL=OFF \
      -DUSE_LCM:BOOL=ON \
      -DUSE_LIBBOT:BOOL=ON \
      -DUSE_SYSTEM_EIGEN:BOOL=ON \
      -DUSE_SYSTEM_LCM:BOOL=OFF \
      -DUSE_SYSTEM_LIBBOT:BOOL=OFF \
      -DUSE_SYSTEM_VTK:BOOL=OFF \
      -DUSE_PCL:BOOL=ON \
      -DUSE_APRILTAGS:BOOL=ON \
      -DUSE_KINECT:BOOL=ON \
      -DCMAKE_INSTALL_PREFIX:PATH=$install_dir \
      -DCMAKE_BUILD_TYPE:STRING=Release

I face the same error . I have libqt4-opengl-dev already installed . I get the following error on running cmake .. I am expecting a normal cmake without error.

ajeya@node1:~/gr-inspector/build$ cmake ..

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.
