我正在尝试在Windows上编译Mangos-Zero项目。
我已经安装了TBB，并将TBB_ROOT_DIR变量设置为：
C:\Users\Administrateur\Downloads\tbb-2018_U2\tbb-2018_U2
然而，该项目找不到它：
CMake Error at CMakeLists.txt:171 (message): This project requires TBB installed. Please download the TBB Stable Release from http://www.threadingbuildingblocks.org/ and install it. If this script didn't find TBB and it was correctly installed please set TBB_ROOT_DIR to the correct path.
通过查看CMake变量集，我看到（screenshot）：
TBB_INCLUDE_DIRS-NOTFOUND
我该怎么办？
