suspicious .pc.cmake file

[tmatth]

The current libzrtpcpp.pc.cmake file generates the following (with the default prefix):

prefix=/usr/local
exec_prefix=/usr/local/bin
libdir=/usr/local/lib64
pkglibdir=${libdir}/pkgconfig
includedir=/usr/local/include
pkgincludedir=${includedir}/pkgconfig

Name: libzrtpcpp
Description: GNU ZRTP core library
Version: 4.2.3
Requires:
Libs:  -L${libdir} -lzrtpcpp
Cflags: -I${includedir}

This is because @PACKAGE@ will evaluate to pkgconfig, which is probably not what was intended. Moreover, anyone compiling against zrtp requires -I {includedir}/libzrtpcpp to be in cflags, otherwise the statement:

#include <ZrtpQueue.h>

will fail with

/usr/include/libzrtpcpp/zrtpccrtp.h:22:23: fatal error: ZrtpQueue.h: No such file or directory
