OK, so what we would have to do (basically):

  - copy Modules/Platform/Linux.cmake to Modules/Platform/Buildroot.cmake

  - tweak that file so that the two settings (lib32 and lib64) are now
    FALSE in that file

  - tweak our support/misc/toolchain.cmake to set(CMAKE_SYSTEM_NAME Buildroot)

and we'd be all good?

Or alternatively:

  - add Modules/Platform/Buildroot.cmake, which:
    - includes Modules/Platform/Linux.cmake
    - sets the the two settings (lib32 and lib64) to FALSE

  - tweak our support/misc/toolchain.cmake to set(CMAKE_SYSTEM_NAME Buildroot)

Thoughts?

Regards,
Yann E. MORIN.
