Only debug version is built

Building Unix console version.
CFLAGS=-g -O2 -std=gnu11
CXXFLAGS=-g -O2
PACKAGE_LIBS= -lm -ldl -lpthread -lpcre

I observed this in Manjaro and MSYS2 and couldn't figure out, why this happens and how to build a release version.

Ah, you are right. The settings must be default from autotools. Looks like this can be overritten like this
./configure CFLAGS="-O2" CXXFLAGS="-O2"
Alternatively you could run the strip command over the exe to remove the debugging symbols.
