pdal ftbfs because cmake on Ubuntu points to multi-arch directories

From the cmake changelog, I don't know if it's obvious but this means that Ubuntu is installing libraries in a different location than Debian if built with cmake:

Compare the output of:
https://buildd.debian.org/status/package.php?p=pdal

-- Installing: /«PKGBUILDDIR»/debian/tmp/usr/lib/pdal/cmake/PDALTargets.cmake

https://launchpad.net/ubuntu/+source/pdal/1.2.0-2

-- Installing: /«PKGBUILDDIR»/debian/tmp/usr/lib/x86_64-linux-gnu/pdal/cmake/PDALTargets.cmake

This later causes pdal to ftbfs because the debian/rules expect the non-multiarch directories.

Hi Jeremy, I'm afraid this is the intended behaviour

cmake (look at the delta) does this:
https://patches.ubuntu.com/c/cmake/cmake_3.5.2-1ubuntu1.patch

+ if(NOT DEFINED CMAKE_INSTALL_LIBDIR)
+ SET(CMAKE_INSTALL_LIBDIR "lib/${CMAKE_LIBRARY_ARCHITECTURE}")
+ endif()

and pdal does:

      if (DEFINED CMAKE_INSTALL_LIBDIR)
          set(PDAL_LIB_INSTALL_DIR "${CMAKE_INSTALL_LIBDIR}")
      else()
          set(PDAL_LIB_INSTALL_DIR "lib")
      endif()

so, this seems to be the reason for this.
what about fixing pdal to be multiarch?

This is fixed in pdal (1.2.0-4).

Libcork is almost fixed in Debian
