pkg-config retrieves information about packages from special metadata files. These files are \u00a0named \u00a0after\u00a0the \u00a0package, \u00a0with \u00a0the extension .pc.
\nBy default, pkg-config looks in the directory\u00a0prefix\/lib\/pkgconfig<\/strong>\u00a0for these files; it will also look in the colon-separated (on Windows, semicolon-separated) list of directories specified by the PKG_CONFIG_PATH environment variable.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
