- add patch 0002-boost-fallback-only-check-for-boost-if-really-needed.patch
to check for boost if really needed (in case of legacy c++ standard < c++17)
Fixes:
- http://autobuild.buildroot.net/results/8d49ab7cd9952f6a13bdd330e875012d0601f1d2
-- Found Boost: .../host/x86_64-buildroot-linux-uclibc/sysroot/usr/include (found version "1.78.0") found components: thread chrono missing components: date_time atomic
CMake Error at .../build/log4cxx-0.12.0/boost-fallback-compile-tests/CMakeFiles/CMakeTmp/CMakeLists.txt:19 (add_executable):
Target "cmTC_aac37" links to target "Boost::date_time" but the target was
not found. Perhaps a find_package() call is missing for an IMPORTED
target, or an ALIAS target is missing?
