-= pkg-config
-The *pkg-config* program is used to retrieve information about installed
-libraries in the system. It retrieves information about packages from special
-metadata files. These files are named after the package, and have a `.pc`
-extension. The package name specified to *pkg-config* is defined to be the name
-of the metadata file, minus the `.pc` extension.

-== Feature: `pkg-config`
-
-Selects one of the initialized `pkg-config` configurations. This feature is
-`propagated` to dependencies. Its use is dicussed in
-section <<pkg-config-init>>.
-
-|# # end::doc[]
-
-feature.feature pkg-config : : propagated ;
-
-
-#| tag::doc[]
-
-== Feature: `pkg-config-define`
-
-This `free` feature adds a variable assignment to pkg-config invocation. For
-example,
-
-[source, jam]
-----
-pkg-config.import mypackage : requirements <pkg-config-define>key=value ;
-----
-
-is equivalent to invoking on the comand line
-
-[source, shell]
-----
-pkg-config --define-variable=key=value mypackage ;
-----
-
-|# # end::doc[]
-
-feature.feature pkg-config-define : : free ;
-
-
-#| tag::doc[]
-
-== Rule: `import`
-
-Main target rule that imports a *pkg-config* package. When its consumer targets
-are built, *pkg-config* command will be invoked with arguments that depend on
-current property set. The features that have an effect are:
-
-* `<pkg-config-define>`: adds a `--define-variable` argument;
-* `<link>`: adds `--static` argument when `<link>static`;
-* `<link>`: adds `--static` argument when `<link>static`;
-* `<name>`: specifies package name (target name is used instead if the property
- is not present);
-* `<version>`: specifies package version range, can be used multiple times and
- should be a dot-separated sequence of numbers optionally prefixed with `=`,
- `<`, `>`, `<=` or `>=`.
-
-Example:
-
-[source, jam]
-----
-pkg-config.import my-package
- : requirements <name>my_package <version><4 <version>>=3.1 ;
-----
-
-|# # end::doc[]
-
-
-rule import
- ( target-name
- : sources *
- : requirements *
- : default-build *
- : usage-requirements *
- )
-{
- param.handle-named-params
- sources requirements default-build usage-requirements ;
- targets.create-metatarget pkg-config-target
- : [ project.current ]
- : $(target-name)
- : $(sources)
- : $(requirements)
- : $(default-build)
- : $(usage-requirements)

-== Initialization [[ pkg-config-init ]]
-
-To use the `pkg-config` tool you need to declare it in a configuration file
-with the `using` rule:
-
-[source, jam]
-----
-using pkg-config : [config] : [command] ... : [ options ] ... ;
-----
-
-
-* `config`: the name of initialized configuration. The name can be omitted, in
- which case the configuration will become the default one.
-* `command`: the command, with any extra arguments, to execute. If no command
- is given, first `PKG_CONFIG` environment variable is checked, and if its
- empty the string `pkg-config` is used.
-* `options`: options that modify `pkg-config` behavior. Allowed options are:
- * `<path>`: sets `PKG_CONFIG_PATH` environment variable;
- multiple occurences are allowed.
- * `<libdir>`: sets `PKG_CONFIG_LIBDIR` environment variable;
- multiple occurences are allowed.
- * `<allow-system-cflags>`: sets `PKG_CONFIG_ALLOW_SYSTEM_CFLAGS`
- environment variable; multiple occurences are allowed.
- * `<allow-system-libs>`: sets `PKG_CONFIG_ALLOW_SYSTEM_LIBS`
- environment variable; multiple occurences are allowed.
- * `<sysroot>`: sets `PKG_CONFIG_SYSROOT_DIR` environment variable;
- multiple occurences are allowed.
- * `<variable>`: adds a variable definition argument to command invocation;
- multiple occurences are allowed.

-
-The class of objects returned by `import` rule. The objects themselves could be
-useful in situations that require more complicated logic for consuming a
-package. See <<pkg-config-tips>> for examples.
-
-. `rule construct ( name : sources * : property-set )`
- Overrides `alias-target.construct`.
-
-. `rule version ( property-set )`
- Returns the package's version, in the context of `property-set`.
-
-. `rule variable ( name : property-set )`
- Returns the value of variable `name` in the package, in the context of
- `property-set`.

-== Tips [[pkg-config-tips]]
-
-
-=== Using several configurations
-
-Suppose, you have 2 collections of `.pc` files: one for platform A, and another
-for platform B. You can initialize 2 configurations of `pkg-config` tool each
-corresponding to specific collection:
-
-[source, jam]
-----
-using pkg-config : A : : <libdir>path/to/collection/A ;
-using pkg-config : B : : <libdir>path/to/collection/B ;
-----
-
-Then, you can specify that builds for platform A should use configuration A,
-while builds for B should use configuration B:
-
-[source, jam]
-----
-project
- : requirements
- <target-os>A-os,<architecture>A-arch:<pkg-config>A
- <target-os>B-os,<architecture>B-arch:<pkg-config>B
- ;
-----
-
-Thanks to the fact, that `project-config`, `user-config` and `site-config`
-modules are parents of jamroot module, you can put it in any of those files.o
-
-
-=== Choosing the package name based on the property set
-
-Since a file for a package should be named after the package suffixed with
-`.pc`, some projects came up with naming schemes in order to allow simultaneous
-installation of several major versions or build variants. In order to pick the
-specific name corresponding to the build request you can use `<conditional>`
-property in requirements:
-
-[source, jam]
-----
-pkg-config.import mypackage : requirements <conditional>@infer-name ;
-
-rule infer-name ( properties * )
-{
- local name = mypackage ;
- local variant = [ property.select <variant> : $(properties) ] ;
- if $(variant) = debug
- {
- name += -d ;
- }
- return <name>$(name) ;
-}
-----
-
-The `common.format-name` rule can be very useful in this situation.
-
-
-=== Modify usage requirements based on package version or variable
-
-Sometimes you need to apply some logic based on package's version or a
-variable that it defines. For that you can use `<conditional>` property in
-usage requirements:
-
-----
-mypackage =
- [ pkg-config.import mypackage : usage-requirements <conditional>@define_ns
- ] ;
-
-rule extra-props ( properties * )
-{
- local ps = [ property-set.create $(properties) ] ;
- local prefix = [ $(mypackage).variable name_prefix : $(ps) ] ;
- prefix += [ $(mypackage).version $(ps) ] ;
- return <define>$(prefix:J=_) ;
-}
