Severity: serious

Hi,

pcl seems to sometimes FTBFS with this error:

Note that -I/.../visualization/include does not appear in the compiler
command like it does on the successful builds.

The top of the log contains this which seems a bit strange:

I had a look at the build system and it seems that "tools" does not
declare a dependency on "visualization" so the order they're built is
random. I think the order depends on the order of directory entries as
chosen by the filesystem driver. This could explain why the build worked
on some buildds.

I haven't managed to build the current version on my amd64 machine at
all (in various different chroots).

Some logs of failed builds (the arm64 one later built successfully):
https://buildd.debian.org/status/fetch.php?pkg=pcl&arch=sparc&ver=1.7.2-6&stamp=1417974163
https://launchpadlibrarian.net/193721902/buildlog_ubuntu-vivid-ppc64el.pcl_1.7.2-6_FAILEDTOBUILD.txt.gz

https://buildd.debian.org/status/fetch.php?pkg=pcl&arch=arm64&ver=1.7.2-3&stamp=1416536853

I've attached a patch which adds the dependency which fixes this issue
for me.

Thanks,
James
