[Bug 1589223] [NEW] MultiArchCross.cmake breaks ubuntuBSD

[Launchpad Bug Tracker]

You have been subscribed to a public bug by LocutusOfBorg (costamagnagianfranco):

debian/MultiArchCross.cmake attempts to set CMAKE_SYSTEM_NAME if it
wasn't already:

  if(NOT DEFINED CMAKE_SYSTEM_NAME)
    if(CMAKE_DEB_HOST_ARCH_OS STREQUAL "linux-gnu")
      SET(CMAKE_SYSTEM_NAME Linux)
    endif()

    if(CMAKE_DEB_HOST_ARCH_OS STREQUAL "kfreebsd")
      SET(CMAKE_SYSTEM_NAME GNU/kFreeBSD)
    endif()
  endif()

However on Linux CMAKE_SYSTEM_NAME is not actually set because
DEB_HOST_ARCH_OS equals linux (not linux-gnu), and the STREQUAL
comparison fails. So no problem there :-)

On ubuntuBSD the comparison succeeds and this breaks things because
setting CMAKE_SYSTEM_NAME forces cmake into cross-compiling mode (see
how CMAKE_CROSSCOMPILING is enabled in CMakeDetermineSystem.cmake). The
resulting package fails to build other packages that need native
compilation (like mysql-5.7).

So could you just remove the whole thing? You can use patch below:
