Would you mind giving me a few more details about your installation? Did you install from source or binary?

Then further, can you verify that you installed poco and pcre correctly from homebrew?
On my machine this looks similar to:

      brew info poco pcre
    poco: stable 1.7.8 (bottled), HEAD
    C++ class libraries for building network and internet-based applications
    https://pocoproject.org/
    /usr/local/Cellar/poco/1.7.8 (784 files, 11.2MB)
      Poured from bottle on 2017-03-08 at 14:15:26
    From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/poco.rb
    ==> Dependencies
    Build: cmake 
    Required: openssl 
    ==> Options
    --with-static
    	Build static libraries (instead of shared)
    --HEAD
    	Install HEAD version

    pcre: stable 8.40 (bottled), HEAD
    Perl compatible regular expressions library
    http://www.pcre.org/
    /usr/local/Cellar/pcre/8.39 (203 files, 5.4MB) *
      Poured from bottle on 2017-02-17 at 09:07:36
    From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/pcre.rb
