I met a compile fail problem, which is caused during parallel build. Please see this bug report for detail:
https://bugs.llvm.org/show_bug.cgi?id=46617

how can I fix this in CMakeList.txt? I have tried to explicitly change target_link_libraries to .so, but during parallel build, if .a is generated first, it is possbile that .a is used, and make the build fail, is this bug of cmake?

Thanks
