Compile error cv_backports

[saspelund]

When compiling ecto_opencv using catkin_make I encountered the following error:

+++ processing catkin package: 'ecto_opencv'
-- ==> add_subdirectory(ecto_opencv)
-- Boost version: 1.54.0
-- Found the following Boost libraries:
--   python
--   thread

CMake Error at /opt/ros/indigo/share/catkin/cmake/catkin_package.cmake:189 (message):

make: *** [cmake_check_build_system] Error 1

This was fixed by adding

<build_depend>cv_backports</build_depend>
and
<run_depend>cv_backports</run_depend>

to package.xml in the ecto_opencv directory.

.

I also saw that in the CMakeLists.txt file it said

find_package(cv_backports QUIET)
if(cv_backports_FOUND)
find_package(catkin REQUIRED ecto opencv_candidate cv_backports)
catkin_package(DEPENDS ecto opencv_candidate cv_backports)
else()
find_package(catkin REQUIRED ecto opencv_candidate)
catkin_package(DEPENDS ecto opencv_candidate)
endif()

so I don't know if my "fix" was correct and proper seeing as I have no idea as to what I am doing.

Right, are you on Indigo ? You need to checkout the Indigo branch then.

Ah. Okay. That is something that I don't know how to do..... I will ask the internet!

Figured it out and catkin_make compiled as expected. Thanks!
