10.2 Header files

Header files are specified by the `HEADERS' family of variables. Generally header files are not installed, so the noinst_HEADERS variable will be the most used. (7)

All header files must be listed somewhere; missing ones will not appear in the distribution. Often it is clearest to list uninstalled headers with the rest of the sources for a program. See section 9.1 Building a program. Headers listed in a `_SOURCES' variable need not be listed in any `_HEADERS' variable.

Headers can be installed in includedir, oldincludedir, or pkgincludedir.
