For large systems, it is often desirable to put sources in a separate
directory from the binaries. The directory search features of
make facilitate this by searching several directories
automatically to find a prerequisite. When you redistribute the files
among directories, you do not need to change the individual rules,
just the search paths.
|• General Search||Specifying a search path that applies
to every prerequisite.
|• Selective Search||Specifying a search path
for a specified class of names.
|• Search Algorithm||When and how search paths are applied.|
|• Recipes/Search||How to write recipes that work together
with search paths.
|• Implicit/Search||How search paths affect implicit rules.|
|• Libraries/Search||Directory search for link libraries.|
