[Help] Using Debian packaged libtbb in r-cran-rcppparallel

[Andreas Tille <andreas@an3as.eu>]

Hi,

I tried to use the Debian packaged libtbb in r-cran-rcppparallel[1].
This worked so far.  However, packages that are using
r-cran-rcppparallel like r-cran-uwot fail to build with

1: In fun(libname, pkgname) : TBB library  not found.
2: In fun(libname, pkgname) : TBB malloc library  not found.

I managed to get the correct linker flags in my last commit[3] but the
warning remains since the code is checking the path to the library
files.  I'd be happy if somebody could please check the patch and fix
the loading of the Debian packaged libtbb.

Kind regards

       Andreas.
