## NOTE: The NEEDED_CXXFLAGS are here so that CXXFLAGS can be specified at build time
## **without** overwriting the CXXFLAGS which we need in order to build.
## For example, when adding 'hardening flags' to the build
## (e.g. -fstack-protector-strong -Wformat -Werror=format-security), we do not want to remove
## -std=c++11. If you want to remove this variable please do so in a way that allows setting
## custom FLAGS to work at build-time.
