TBB needs pkg-config or similar interface for easy embedding into applications

[anton-malakhov]

Continuum Analytics feedback: Exposing a pkg-config interface for TBB, or something similar (such as llvm-config), sounds like a good way to avoid hard-coding environment-related definitions in every third party project.
TBBROOT is not enough in order to configure application with correct compiler and linker flags needed to build an application which uses TBB.
See the issues related in this PR: numba/numba#2217 (review)

For more information see https://people.freedesktop.org/~dbn/pkg-config-guide.html
It can be done for binary TBB package and can be generated as yet another kind of tbbvars during the build from sources

Hi,
Are there still plans for introducing pkg-config files into TBB?
Few our engines depend on the TBB and pkg-config will significantly improve experience while working with custom installation paths.
Best regards,

Hi @KFilipek, thank you for reminding about this issue! I don't have any experience in writing pkg-config files, but I can investigate this topic. It may require some time since I'm pretty busy with other activities; feel free to submit a PR or just put a snapshot here if you already have something as your local solution.

@KFilipek, let me duplicate the question from PR #361:

Is it enough for you to have pkg-config support for build from sources only? Are you interested in having it in prebuilt packages from release page (not sure how to dynamically get prefix value in this case)?

[AlexVeprev]

oneAPI packages (including oneTBB) now have support of pkg-config.

How does it apply to tbbmalloc, can that also be easily configured/linked with using the added pkg-config support?
