poppler-25.07.0 FTBFS without gpgmepp-2.0.0

[Joe Locash]

With the update to gpgme-2.0.0 poppler now fails to build without gpgmepp:

CMake Warning at CMakeLists.txt:163 (find_package):
  By not providing "FindGpgmepp.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Gpgmepp", but
  CMake did not find one.

  Could not find a package configuration file provided by "Gpgmepp"
  (requested version 1.19) with any of the following names:

    GpgmeppConfig.cmake
    gpgmepp-config.cmake

  Add the installation prefix of "Gpgmepp" to CMAKE_PREFIX_PATH or set
  "Gpgmepp_DIR" to a directory containing one of the above files.  If
  "Gpgmepp" provides a separate development package or SDK, be sure it has
  been installed.

CMake Error at CMakeLists.txt:165 (MESSAGE):
  Could not find the 1.19 version of Gpgmepp.  If you're not interested in
  the features it provides set the cmake ENABLE_GPGME option to OFF

gpgme is recommended in poppler but no mention of gpgmepp.

OK, that's a very easy fix.

Fixed at commit 5f739f804b.
