I have a question regarding how to pass extra arguments(such as cflags) from maven release plugin to native-maven-plugin. We use codehaus native-plugin to build jni, I want to pass the cflags during release phase. However I see that I am unable to pass any of the arguments through release plugin. Any experience or pointers would help
```
scalareleasedryrun:
(cd $(ROOTDIR)/scala-package; \
mvn -X release:prepare -DdryRun=true -DautoVersionSubmodules=true \
-P$(SCALA_PKG_PROFILE),$(SCALA_VERSION_PROFILE) \
-Darguments=-DskipTests -Dcxx="$(CXX)" \
-Dcflags="$(CFLAGS)" -Dldflags="$(LDFLAGS)" \
-Dlddeps="$(LIB_DEP) $(ROOTDIR)/lib/libmxnet.a")
```
The parent pom file is here
I see that cflags variable used in the native pom.xml is coming as null
