Since Buildroot commit dcee99507c that
bumped package/icu to version 77-1, the build of cppcms with ICU
support enabled fails.
Indeed, ICU now requires C++17, and while cppcms.mk has some logic to
get C++ flags using icu-config, the -std=c++17 gets ultimately
overridden by the built-in -std=c++11 flag encoded in cppcms
CMakeLists.txt.
To fix this, we have submitted a patch upstream that ensures the
CMAKE_CXX_FLAGS passed on the command line take precedence over the
built-in flags defined in cppcms CMakeLists.txt.
