The value of ${includedir} is going to be something like
/usr/include (GNU/Linux)
/usr/local/include (FreeBSD ports)
/usr/local/Cellar/readline/8.0.0/include (macOS homebrew)
and software using readline is supposed to
#include <readline/readline.h>
However, since Cflags in readline.pc contains
-I${includedir}/readline
the compiler will expect to find the header in
/usr/include/readline/readline/readline.h
which will work on GNU/Linux, where /usr/include is part of the
default include path, but will not on other platforms.
