Compilation fails for pano_core

[bchretien]

When compiling pano_core on Arch Linux, I get a ton of linker errors:

Scanning dependencies of target stitcher
[100%] [100%] Building CXX object CMakeFiles/stitcher.dir/apps/stitcher.cpp.o

...

My patch currently involves adding this to CMakeLists.txt:

find_package(OpenCV REQUIRED)

This may be an error in opencv2 or cv_bridge, since include directories/libraries may be passed down to dependencies.

The package uses opencv library directly. your comment is right. Can you make a pull request to fix?

[bchretien]

@jihoonl done ;-)

I believe this is closed.
