I am seeing this library under the vc14 directory. It is not present in the vc12 or previous versions. Is this a static library and does not require linking to the dynamic library (tbbmalloc.dll)?
right, this is the static library. It was added to the package by mistake and will be removed. thanks for reporting this.
Also what is the difference between the vc12 and vc12_ui folders?
*_ui folders contain binaries for windows store apps. vc12 folder contains regular binaries for desktop apps
