The package_home.h header

#include "prjlibs-include/package_home.h"

The package_home.h C header file defines a PACKAGE_HOME macro specifying the user-configured path to the package directory. C programs can use this path at runtime to find other files belonging to the package. The header is automatically generated at compile time by a mkmed build script. You can include it in your project by borrowing from the /package/prog/prjlibs/include directory to pull in the source files that package_home.h is built from.
