title: pygobject-2.28.6 won't configure: No package 'gobject-introspection-1.0' found, how do I resolve?
body: <p>I'm trying to get pygobject-2.28.6 to compile in cygwin (version in repository is 2.28.4 which has some issues). Here is the tail of ./configure:</p>
  
  <pre><code>checking for GLIB - version &gt;= 2.24.0... yes (version 2.34.3)
  checking for ffi... checking for FFI... yes
  checking for GIO... yes
  checking for GIOUNIX... yes
  checking for GI... no
  configure: error: Package requirements (glib-2.0 &gt;= 2.24.0
          gobject-introspection-1.0 &gt;= 0.10.2
      ) were not met:
  
  No package 'gobject-introspection-1.0' found
  
  Consider adjusting the PKG_CONFIG_PATH environment variable if you
  installed software in a non-standard prefix.
  
  Alternatively, you may set the environment variables GI_CFLAGS
  and GI_LIBS to avoid the need to call pkg-config.
  See the pkg-config man page for more details.

  <p>I have gobject-introspection 1.34.2-3 installed. As seen here:</p>
  
  <pre><code>$ whereis gobject-introspection
  gobject-introspection: /lib/gobject-introspection /usr/lib/gobject-introspection
  </code></pre>
  
  <p>and here</p>
  
  <pre><code>$ whereis gobject-introspection-1.0
  gobject-introspection-1: /usr/share/gobject-introspection-1.0
  </code></pre>
  
  <p>I've tried setting GI_CFLAGS and GI_LIBS in configure = to /lib/ and /usr/lib/ (and even /usr/share/) but to no avail. What else can I do to try and resolve this? Thank you for your time!</p>
