Albert,
If you can make a patch to the FindGDAL.cmake that does this, I'm happy to include it. We should also upstream it to Kitware, as I think they use our FindGDAL.cmake that was originally written by Mateusz.
gdalinfo --version doesn't seem to output any install location information for me for either GDAL 1.11.x or GDAL 2.0.x, so I'm not sure about how to implement this patch myself.

That information it totally different from the one where gdal is installed. A better approach would be to use “gdalinfo —version” to find out the version being used, and extract the directory location for include and lib from the full path of the gdalinfo command (or from the GDAL_HOME environment variable if one is set).

In other words "gdal-config —libs” returns the location of the libraries as they were on the system where GDAL was built, and subsequently GDAL_LIBRARY is set to an invalid location too, definitely not the one used in the current GDAL installation.

>>> /me groans. There's a boost 1.60 now? Consider this notice that it is a medium term goal of the PDAL project to eliminate its dependence on externally available Boost before its 2.0 release. Now that C++11 is quite stable just about everywhere, the impetus to reach for Boost for everything is not there anymore for PDAL. Their project release management leaves much to be desired, and because of it, packaging maintainers lag many versions behind current releases.
