Description of problem:

The package config file install is missing important path information.

----------------------------------------------------------------------------------------
$ more /usr/i686-w64-mingw32/sys-root/mingw/lib/pkgconfig/libzip.pc
prefix=
exec_prefix=
libdir=
includedir=
libincludedir=/libzip/include

zipcmp=/bin/zipcmp

Name: libzip
Description: library for handling zip archives
Version: 1.1
Libs:  -L${libdir} -lzip -lz
Cflags: -I${includedir} -I${libincludedir}
----------------------------------------------------------------------------------------

Clearly prefix etc. are not set correctly.  Should read more like:

prefix=/usr/i686-w64-mingw32/sys-root/mingw
exec_prefix=/usr/i686-w64-mingw32/sys-root/mingw
libdir=/usr/i686-w64-mingw32/sys-root/mingw/lib
includedir=/usr/i686-w64-mingw32/sys-root/mingw/include
libincludedir=/usr/i686-w64-mingw32/sys-root/mingw/lib/libzip/include

The issues seems to be use of cmake for this build without running the
configure script as is done for "native" builds.  The configure script
properly makes the .pc file from the .pc.in file with the proper
substitutions.

Version-Release number of selected component (if applicable):

Seems broken in rawhide, too.  Used to be right in Fedora 22.

Actual results:

Result is, build systems that use pkg-config end up horked.
