_has_include() breaks TBB compilation when other software have <version> files in include search path

[per-mathisen-arm]

Summary

Recently TBB added a conditional include of the file <version> at https://github.com/oneapi-src/oneTBB/blob/master/include/oneapi/tbb/detail/_config.h#L31 from commit https://github.com/oneapi-src/oneTBB/commit/4cc1ccac6f00bd57ceee5325ad9f2593b20bb046

This means that if any app that uses TBB itself has a file called <version> in its include path, or one of its other dependencies has this, then it will include this other file and most likely break compilation - or worse, succeed but include the wrong code.

I encountered this issue compiling an app that uses jsoncpp with tbb, and jsoncpp happens to have its own <version> file in its include path which breaks tbb compilation.

Version

Bundled version in Ubuntu 24.04.1 and also OneAPI git master branch.

Environment

N/A

Observed Behavior

Broken compilation

Expected Behavior

Successful compilation

Steps To Reproduce

You could try to compile https://github.com/arm-software/lavatube on Ubuntu 24.04.1

Recommended action: Add additional search paths to _has_include to prevent accidental includes of other <version> files.
