gradle_native_global_definitions
Demonstrating how to have a common definition in Gradle nested projects.
The nested projects should use the cpp compiler options from the base project.
Trick is to use allprojects in the root.
To run:
docker build --build-arg VERSION=4.8 -t test .
where 4.8 is the version of gradle you want to test.
This technique was changed starting with gradle 2.9.
