# CMake looks first at swig3.0, then swig2.0 and then swig. However,
# when doing the search, it will look into the PATH for swig2.0 first,
# and then for swig.
# While the PATH contains first our $(HOST_DIR)/bin, it also contains
# /usr/bin and other system directories. Therefore, if there is an
# installed swig3.0 on the system, it will get the preference over the
# swig installed in $(HOST_DIR)/bin, which isn't nice. To prevent
# this from happening we create a symbolic link swig3.0 -> swig, so that
# our swig always gets used.
