So far, the cmake files of Cppcheck needed to be patched in order to
use installed tinyxml2 instead of the bundled version of tinyxml2.
- Introduce the CMake option USE_BUNDLED_TINYXML2 with a default value
of ON. This preserves the behavior as in the past and uses the
bundled version under externals/tinyxml2 by default.
- Usage of the installed tinyxml2 version of a system can be enabled
now using -DUSE_BUNDLED_TINYXML2=OFF as a cmake parameter.
- Some Linux distros do not install tinyxml2*.cmake files, which are
required to find tinyxml2 using find_package().
Try first using find_package(tinyxml2 QUIET) and if this fails, try
again using find_library(tinyxml2_LIBRARY tinyxml2)
* cleaned up compiler options related code in CMake
* moved cmake_minimum_required() and raised to latest 2.8.x version
* use proper compiler version check / print compiler version
* fixed linking of sanitized builds
* added proper version checks to newer Clang warnings and enabled them / moved tinyxml_objs flags to proper compiler
* disabled -Wdeprecated-declarations for Clang
* compileroptions.cmake: removed unnecessary check for clang++ existence - CMAKE_CXX_COMPILER_ID is determined by CMake
* printInfo.cmake: removed unnecessary message for ANALYZE_ADDRESS - LSAN is part of ASAN and enabled by default
* cleaned up if() comparisons in CMake
* added/adjusted TODOs
* excluded oss-fuzz related CMake targets from all
* checkstl.cpp: fixed -Wmissing-declarations warning
* suppress -Wsuggest-attribute=format GCC warnings for tinyxml in CMake for now
* aligned GCC warnings in dmake, CMake and Travis / removed now useless WARNINGS_ANSI_ISO
From CMake Docs( https://cmake.org/cmake/help/latest/variable/BUILD_SHARED_LIBS.html ),
BUILD_SHARED_LIBS may not be defined. This can result in printinfo.cmake outputing
variable without a value. A conditional is applied to ensure that some output is
provided to the user should variable not be defined.
Removed explicit C++ standard flag. Any setting user would add on the command
line would be replaced due to ordering. `-std=c++0x` would be last value added
to CMAKE_CXX_FLAGS and ultimately the one used by the compiler.
Update CMake search for Qt5 componets to be consistent
with recommended practice from Kitware.
(see https://blog.kitware.com/cmake-finding-qt5-the-right-way/)
Incorporate ability to build cppcheck-gui with Qt Charts
via CMake switch. Option "WITH_QCHARTS" will enable
search for Qt Charts to Qt5 component search and add
build flag "HAVE_QCHART".
