# There now follow some tests for QtCore, Boost, and OpenMP. These
# tests are present because Drd has some regression tests that use
# these packages. All regression test programs all compiled only
# for the primary target. And so it is important that the configure
# checks that follow, use the correct -m32 or -m64 flag for the
# primary target (called $mflag_primary). Otherwise, we can end up
# in a situation (eg) where, on amd64-linux, the test for Boost checks
# for usable 64-bit Boost facilities, but because we are doing a 32-bit
# only build (meaning, the primary target is x86-linux), the build
# of the regtest programs that use Boost fails, because they are
# build as 32-bit (IN THIS EXAMPLE).
#
# Hence: ALWAYS USE $mflag_primary FOR CONFIGURE TESTS FOR FACILITIES
# NEEDED BY THE REGRESSION TEST PROGRAMS.
# The test below verifies whether the QtCore package been installed.
# This test works as follows:
# - If pkg-config was not installed at the time autogen.sh was run,
# the definition of the PKG_CHECK_EXISTS() macro will not be found by
# autogen.sh. Augogen.sh will generate a configure script that prints
# a warning about pkg-config and proceeds as if Qt4 has not been installed.
# - If pkg-config was installed at the time autogen.sh was run,
# the generated configure script will try to detect the presence of the
# Qt4 QtCore library by looking up compile and linker flags in the file
# called QtCore.pc.
# - pkg-config settings can be overridden via the configure variables
# QTCORE_CFLAGS and QTCORE_LIBS (added by the pkg-config m4 macro's to the
# configure script -- see also ./configure --help).
# - The QTCORE_CFLAGS and QTCORE_LIBS configure variables can be used even if
# the pkg-config executable is not present on the system on which the
# configure script is run.
