|
|
Usage
|
...
|
ffibuilder.set_source("_foo", pkgconfig = ["libfoo", "libbar >= 1.8.3"])
|
|
If pkg-config is installed on build machine, then arguments include_dirs,
|
library_dirs, libraries, define_macros, extra_compile_args and
|
extra_link_args are extended with an output of pkg-config for libfoo and
|
libbar.
|
|
Raises PkgConfigError in case the pkg-config call fails.
