Lower/Mixed/Upper case of system root directory, "ReactOS", for both BootCD/LiveCD

It seems Windows uses upper case for a few directories (and files).

For example:

Windows XP: WINDOWS RECYCLER NTDETECT.COM

ROS BootCD: ReactOS RECYCLED

ROS LiveCD: reactos

In this issue, I am interested in system root directory only.
Which case should we use? REACTOS, ReactOS or reactos?

BootCD itself has reactos, but, once installed, HDD has ReactOS.
LiveCD itself has reactos too, which, once booted, is used as is.

LiveCD case:

$ ninja -v livecd

[3/3] cd .../output-MinGW-i386/reactos/boot && .../mkisofs ... .../livecd.lst ...

sdk/cmake/CMakeMacros.cmake

 165 macro(dir_to_num dir var)

 166     if(${dir} STREQUAL reactos/system32)

 167         set(${var} 1)

 ...

 277 function(add_cd_file)

 ...

add_cd_file grep

add_cd_file(TARGET atactl DESTINATION reactos/system32 FOR all)

...

Would there be a simple solution to rename reactos to ReactOS at build time?
Or would we have to update all add_cd_file() calls in source?
