libept fails to cross build from source. I don't quite understand the
failure mode. It seems that CMAKE_LIBRARY_ARCHITECTURE ends up being
empty than thus dh_install fails. While trying to understand the
problem, I noticed that the main CMakeLists.txt has an explicit cc
invocation. That's bad, because it examines the build architecture
instead of the host architecture. Surprisingly replacing that single
call with ${CMAKE_C_COMPILER} (which should have been used in the first
place) makes the cross build just work. Please consider applying the
attached patch.
