Bug description:
[Impact]
* This bug prevents users to link dynamically against pcl libraries
* There is no upload required as rebuilding the package is enough to fix the
bug
[Test Case]
* install libpcl-dev
* apt-get update && apt-get install libpcl-dev
* mkdir -p /tmp/test_pcl/src && cd /tmp/test_pcl
* echo "#include <pcl/common/io.h>" > src/foo.cpp
* create a CMakeLists.txt
```
find_package(PCL REQUIRED)
option(BUILD_SHARED_LIBS "Build shared libs" ON)
include_directories(${PCL_INCLUDE_DIRS})
add_library(foolib src/foo.cpp)
target_link_libraries(foolib ${PCL_LIBRARIES})
```
* mkdir build && cd build
* cmake ..
* make
This produces the error message:
```
make[2]: *** No rule to make target '/usr/lib/libmpi.so', needed by
'libfoolib.so'. Stop.
CMakeFiles/Makefile2:67: recipe for target 'CMakeFiles/foolib.dir/all' failed
make[1]: *** [CMakeFiles/foolib.dir/all] Error 2
```
[Patch]
* Rebuild the package
* Test case passes once the package rebuilt
[Regression Potential]
* Given that the patch is just a rebuild I don't see a potential for
regression
Package: libpcl-dev (1.8.0+dfsg1-4ubuntu4) (on Zesty)
Source of the bug: last build of vtk6 exports libmpi.so in
/usr/lib/x86_64-linux-gnu/openmpi/lib and not /usr/lib/openmpi/lib
anymore.
Impact: unable to link libraries against pcl-dev without [hacky
workaround](https://github.com/ros-
perception/perception_pcl/commit/42683bd4069c3a8bcec56d6c4e686d9e8643e77b)
Changelog introducing the bug:
```
vtk6 (6.3.0+dfsg1-3) unstable; urgency=medium
* Rebuild against new multiarch enabled openmpi, Closes: #848785
```
Solution: rebuild libpcl-dev against libvtk6-dev (6.3.0+dfsg1-3)
Thanks!
