When building projects such as those interacting with the JNI, you need access to a few header files located in a Java installation. This system dependency will add the correct include paths to your target. It assumes that either JAVA_HOME will be set to a valid Java installation, or the default javac on your system is a located in the bin directory of a Java installation. Note: symlinks are resolved.
jdk = dependency('jdk', version : '>=1.8')
Currently this system dependency only works on linux, win32, and darwin. This can easily be extended given the correct information about your compiler and platform in an issue.
