# Do not use the CMake build rules provided by compiler-rt. The CMake build
# rules shipped with compiler-rt depend both on a standard C++ library and a
# compiler that can generate working executables. In our case we are not
# capable of generating executables, for the reason that we need an installed
# copy of compiler-rt.
#
# Fall back to generating the object files and the library manually.
