Hi, I'm using Mac OSX Yosemite, still trying to install ROS Indigo, and I've decided to move on from my last error (for the reason I gave here. So now my error is that, during the $ ./src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release step, I get the error(s?)

 CMake Error at CMakeLists.txt:5 (find_package):
  By not providing "Findurdfdom_headers.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "urdfdom_headers", but CMake did not find one.

  Could not find a package configuration file provided by "urdfdom_headers"
  with any of the following names:

    urdfdom_headersConfig.cmake
    urdfdom_headers-config.cmake

  Add the installation prefix of "urdfdom_headers" to CMAKE_PREFIX_PATH or
  set "urdfdom_headers_DIR" to a directory containing one of the above files.
  If "urdfdom_headers" provides a separate development package or SDK, be
  sure it has been installed.

<== Failed to process package 'urdf_parser_plugin':

Reproduce this error by running:
==> cd /Users/School/ros_catkin_ws/build_isolated/urdf_parser_plugin && /Users/School/ros_catkin_ws/install_isolated/env.sh cmake /Users/School/ros_catkin_ws/src/robot_model/urdf_parser_plugin -DCATKIN_DEVEL_PREFIX=/Users/School/ros_catkin_ws/devel_isolated/urdf_parser_plugin -DCMAKE_INSTALL_PREFIX=/Users/School/ros_catkin_ws/install_isolated -DCMAKE_BUILD_TYPE=Release -G 'Unix Makefiles'

which I assume has to do with my ignoring my last issue. So, is there a way to make everything that has to do with urdfdom be ignored during this [and future] steps? Thanks.
