# ${LIB_DIRS} variable contains a list of directories, each of them
# containing a library that must be linked with programs in the
# current directory. The library in the directory 'dir' must be called
# 'dir/libdir.a'. We assume that the 'dir' directory contains a Makefile
# to build a corresponding library, and simply do 'make -C dir libdir.a'
# if the library does not exist. If the library exists, we will use
# whatever it contains, without checking its dependencies. To build the
# up-to-date libraries in ${LB_DIRS} directories use 'make libs' command.
# We omit the check of library dependencies just for speed; if the library
# is actively changed and must be constantly recompiled, one should use
# ${OTHER_DIRS} variable to include the *.c files of that directory
# into the compilation list.
