cmake: fix the build of tests

[tchaikov]

perfglue/heap_profiler.cc is referncing boost-system somehow, and
this file is compiled when we are using tcmalloc, so added it to
ALLOC_LIBS along with tcmalloc.

@cbodley again, could you help me on this? thanks =)

i think this change was introduced by the graylog changes in #7190, i failed to reproduce the compilation error spotted by @irq0 . but it popped up in our gitbuilder at last.

[cbodley]

@tchaikov do you have a link to the gitbuilder log?

thanks @tchaikov. i also can't figure out why boost_system is getting pulled in - a grep for 'system_category' on our source tree came up empty.

i get the feeling the cmake build is getting this heap_profiler stuff horribly wrong. i read through the automake files, and all they do is build a libperfglue.la and add it to LIBOSD/LIBMON/LIBMDS. we should eventually do an audit on this stuff in cmake to make sure we get it right, but i'm fine with merging your fix in the meantime

[tchaikov]

@cbodley root caused and fixed it.

[tchaikov]

hey @alimaredia could you help review it?

[alimaredia]

@mattbenjamin didn't you say we needed to do the two points Kefu mentioned in his previous post?

[tchaikov]

pushed for testing at http://gitbuilder.sepia.ceph.com/gitbuilder-ceph-tarball-trusty-amd64-cmake/#origin/wip-fix-cmake, and it's green.

[cbodley]

@tchaikov good catch!

@alimaredia those two changes are no longer needed after this fix

[alimaredia]

@tchaikov ${Boost_LIBS} neither in /usr/share/cmake/modules/FindBoost.cmake nor anywhere else in the source tree. It should be changed to ${Boost_LIBRARIES}

[tchaikov]

@alimaredia could you take a look again? I just removed ${Boost_LIBS} .

[tchaikov]

tested at http://gitbuilder.sepia.ceph.com/gitbuilder-ceph-tarball-trusty-amd64-cmake/#origin/wip-fix-cmake , green also.
