There was a problem hiding this comment.
Observations:
- direct invocation of link.exe/cl.exe works fine (with setvars.bat)
- invocation through MSBuild doesn't work
Reason: MSBuild drops/replaces some environment variables, including LIB which points to TBB's library directory (specified in setvars).
