Describe the bug
Probably not a bug in itself, but I'm logging this here: I just tried to rebuild using ninja & gcc 11. With the default being PCH=On, I sometimes see:
cc1plus: error: /MK404/build/CMakeFiles/MK404.dir/cmake_pch.hxx.gch: created and used with differing settings of '-mrtm' [-Werror=invalid-pch]
This is misleading though. I guess that -mrtm is actually toggled by a different optimization level somewhere. Or maybe it's actually a bug in gcc 11. And since ninja tends to run things more parallel-ly than make, you get this.
ninja -j1 will clear this, as well as disabling pch, as well as just using make ;)
To Reproduce
Use cmake -G Ninja, gcc 11 and ninja -j>5 when building.
Expected behavior
No build failure even when PCH is enabled.
Desktop (please complete the following information):
Additional context
I might debug this later myself, just logging this for reference.
