The default pkg-config tool may be changed by setting the PKG_CONFIG environment variable.

For security reasons, only a limited set of flags are allowed, notably -D, -U, -I, and -l.
To allow additional flags, set CGO_CFLAGS_ALLOW to a regular expression
matching the new flags. To disallow flags that would otherwise be allowed,
set CGO_CFLAGS_DISALLOW to a regular expression matching arguments

## Context

[Gradle properties](https://docs.gradle.org/current/userguide/build_environment.html#sec:gradle_configuration_properties)
are flags that allow build engineers to opt into and out of features of Gradle Runtime or Core Plugins.
Practically every Gradle feature is behind a flag, and additional sub-flags or options provide further control.
