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
    /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
    	Build static libraries (instead of shared)
    	Install HEAD version

    pcre: stable 8.40 (bottled), HEAD
    Perl compatible regular expressions library
    /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
