I was trying to build KiCad with the Python scripting enabled and was getting a swig error during configuration. I ran the command:
$ swig.exe -swiglib
/mingw64/bin/swig.exe: error while loading shared libraries: libpcre-1.dll: cannot open shared object file: No such file or directory
and discovered that libpcre-1.dll was indeed missing. I installed the libprce package and the problem was resolved. It appears that libprce is not defined as a dependency of the swig package.
Thanks, will fix dependencies.
