Bug#916913: libpcl-dev: PCLConfig.cmake fails to find eigen

[Johannes 'josch' Schauer]

Package: libpcl-dev
Version: 1.9.1+dfsg1-2
Severity: grave
Justification: renders package unusable

Hi,

a CMakeLists.txt with "find_package(PCL REQUIRED)" will currently result in:

CMake Warning at /usr/lib/x86_64-linux-gnu/cmake/pcl/PCLConfig.cmake:159 (find_package):
  By not providing "FindEigen.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Eigen", but
  CMake did not find one.

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

    EigenConfig.cmake
    eigen-config.cmake

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

But libeigen3-dev is installed. For a full failing build log see:

Thanks!
