That QGpgme is not found with gpgme 1.7.X directly via (find_package) is a bug, that will be closed with 1.7.2. so don't rely at this behaviour. but the name is QGpgme_FOUND should be definded after find_package(Gpgmepp). So you can test if (QGpgme_FOUND or QGPGME_FOUND) to test for QGpgme support.
