Compile when bfl is a dependency in melodic

[FrGe2016]

I am trying to compile wg_perception/peoples

The people_tracking_filter has orocos-bf as a dependency
# Look for bfl (Bayesian Filtering Library)
find_package(PkgConfig)
pkg_check_modules(BFL REQUIRED orocos-bfl)

If i understand well in the Melodic i have ros-melodic-bfl that would be a "version" of orocos-bfl
It is installed in my PC but not recognised as a ros package ?
roscd ros-melodic-bfl or roscd bfl gives roscd:
No such package/stack 'xxxxxx'
so even if i modify the cmakelist.txt for one of these i still get an error?

It is not the first time that i have a problem with that dependency with orocos-bfl.
All the time a gave up at the end ?

Has this been solved?

I am working on something else for the moment but this problem has not been solved.
