With MacPorts and a patched cmake I am able to configure py27-pyside.

Here is the working cmake command MacPorts is producing; maybe it will help you:
cmake -DCMAKE_INSTALL_PREFIX=/opt/local -DCMAKE_VERBOSE_MAKEFILE=ON -DCMAKE_COLOR_MAKEFILE=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_BUILD_WITH_INSTALL_RPATH=ON -DCMAKE_INSTALL_NAME_DIR=/opt/local/lib -DCMAKE_SYSTEM_PREFIX_PATH="/opt/local;/usr" -DCMAKE_MODULE_PATH=/opt/local/share/cmake/modules -Wno-dev -DBUILD_TESTS:BOOL=FALSE -DPYTHON_EXECUTABLE=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7 -DPYTHON_LIBRARY=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python -DPYTHON_INCLUDE_DIR=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -DSITE_PACKAGE=/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages -DCMAKE_OSX_ARCHITECTURES="x86_64" -DCMAKE_OSX_SYSROOT:PATH=/Developer/SDKs/MacOSX10.6.sdk
