Bug 296867

The top level CMakeLists.txt for kdenetwork checks for the optional presence of QCA2:

macro_optional_find_package(QCA2)
macro_log_feature(QCA2_FOUND "QCA2" "Qt Cryptographic Architecture" "http://delta.affinix.com/qca" FALSE "2.0.0" "Needed for the KGet bittorrent-plugin and some Kopete plugins")

and indeed does not complain if it is not found:

-----------------------------------------------------------------------------
-- The following OPTIONAL packages could NOT be located on your system.
-- Consider installing them to enable more features from this software.
-----------------------------------------------------------------------------
   * QCA2 (2.0.0 or higher)  <http://delta.affinix.com/qca>
     Qt Cryptographic Architecture
     Needed for the KGet bittorrent-plugin and some Kopete plugins

However, the kget/tests appears to unconditionally require QCA2:

#===========Verifier===========
kde4_add_unit_test(verifiertest
  TESTNAME kget-verifiertest
  verifiertest.cpp
)
target_link_libraries(verifiertest ${QT_QTTEST_LIBRARY} ${KDE4_KDECORE_LIBS} ${QCA2_LIBRARIES} kgetcore)

and the configuration fails if QCA2 is not available:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
QCA2_LIBRARIES (ADVANCED)
    linked by target "verifiertest" in directory /ws/trunk/kdenetwork/kget/tests
-- Configuring incomplete, errors occurred!

The optional/required status should be consistent between kdenetwork and kget.
