# swipl uses cmake macros try_run() and check_c_source_runs(), which
# are not suitable for cross compilation. We add results in cache to
# avoid running those tests. The SWIPL_NATIVE_FRIEND variable, is
# meant to point to build directory of a host native swipl, rather
# than the binary itself. The Cmake macro will append "src/swipl" to
# the path set to this variable. Therefore, we cannot use the host
# "swipl" binary installed in $(HOST_DIR)/usr/bin.
