I think it's because clang doesn't know about -mthreads.

The CMake setup finishes successfully. When I invoke clang++ with the options:<br>
<br>
-c -x c++ -O0 -g -fno-inline -Wall -g -mthreads<br>
<br>
I get:<br>

clang++.exe: error: unknown argument: &#39;-mthreads&#39;<br>

Is this because of either of the problems beforehand when CMake wqas used ? If so how \
do I correct the CMake problems ?<br> <br>
