libpkgconf `pkg` module
|
||||
=======================
|

The `pkg` module provides dependency resolution services and the overall `.pc` file parsing

||||
routines.

|
||||
|
||||
Bootstraps the package search paths. If the ``PKGCONF_PKG_PKGF_ENV_ONLY`` `flag` is provided,
|
||||
then only the ``PKG_CONFIG_PATH`` environment variable will be used, otherwise both the
|
||||
``PKG_CONFIG_PATH`` and ``PKG_CONFIG_LIBDIR`` environment variables will be used.
