Alessandro Menti 86fb1ed00f BoostTestTargets.cmake: fix a wrong include test 
BoostTestTargets.cmake requires the CMake-configurable form of the Boost
test framework to be used (i.e. "#include <BoostTestTargetConfig.h>"), and
checks each test source code file for this, outputting a warning in case
this requirement is not met.

Unfortunately, a conditional in the check is badly specified (the CMake
variable syntax is not followed), so the warning is emitted even when it
should not be.

This patch fixes this bug and restores the correct behavior.

# - Add tests using boost::test
#
# Add this line to your test files in place of including a basic boost test header:
# #include <BoostTestTargetConfig.h>
#
# If you cannot do that and must use the included form for a given test,
# include the line
# // OVERRIDE_BOOST_TEST_INCLUDED_WARNING
# in the same file with the boost test include.
#
# include(BoostTestTargets)
# add_boost_test(<testdriver_name> SOURCES <source1> [<more sources...>]
# [FAIL_REGULAR_EXPRESSION <additional fail regex>]
# [LAUNCHER <generic launcher script>]
# [LIBRARIES <library> [<library>...]]
# [RESOURCES <resource> [<resource>...]]
# [TESTS <testcasename> [<testcasename>...]])
#
# If for some reason you need access to the executable target created,
# it can be found in ${${testdriver_name}_TARGET_NAME} as specified when
# you called add_boost_test
#
# Requires CMake 2.6 or newer (uses the 'function' command)
#
# Requires:
# GetForceIncludeDefinitions
# CopyResourcesToBuildTree
