foo.cpp
D:\tmp>sccache cl /c foo.cpp "/Fo.\\"
sccache: encountered fatal error
sccache: error: failed to zip up compiler outputs
sccache: caused by: failed to zip up compiler outputs
sccache: caused by: failed to open file `"D:\\tmp\\.\\"`
sccache: caused by: failed to open file `D:\tmp\.\`
sccache: caused by: The system cannot find the path specified. (os error 3)
D:\tmp>type foo.cpp
