.. and many more.
libmpdclient, libmicrohttpd and jsoncpp provide a .pc file. Use
pkg-config for detecting the libraries and for providing the necessary
details for compiling and linking.
The current build system of upmpdcli does not use PKG_CHECK_MODULES, but
AC_LINK_IFELSE to detect jsoncpp. After bumping jsoncpp version from
1.7.2 to 1.7.5 the detection fails, because the test program does not
compile anymore:

Instead of fixing the test program use PKG_CHECK_MODULES to check for
jsoncpp. While we're on it, add it for libmpdclient and libmicrohttpd,
too.
