Sorry for the late reply. I am told that StanHeaders can be built successfully with oneTBB by setting environmental variables like TBB_INC and TBB_LIB. On CRAN, we would like to use the version of TBB that comes with the RcppParallel package [...]
Thanks for the pointers, but we are able to build cppparallel and stanheaders without problems as is. But the built package is unusable as it uses "#include" statements that try to include files available in older tbb but not in new onetbb, as observed in rstan compilation. The problematic #include statment (and corresponding removed APIs) seems to be stemming from "inst/include/stan/math/prim/core/init_threadpool_tbb.hpp" On taking a deeper look, I observed that this is directly embedded from stan/math[1] The current release of stanheaders contains an older copy of the math lib. Going fwd, a patch had been added to stan/math to make it compatible with onetbb[2] On cherry-picking a couple of changes from there, I am able to get rstan to compile. I am not very sure if everything is good/works as expected (autopkgtests / CRAN tests seem to pass, so that's a good indication), but I'd be thrilled to believe so.
