The CFLAGS and CXXFLAGS variables define the build and compile flags that will be used for all package deployments (some exceptions notwithstanding who filter out flags known to cause problems with the package). The CFLAGS variable is for C based applications, while CXXFLAGS is meant for C++ based applications. Most users will keep the content of both variables the same.
