 159 Help options:
 160   --help                   print this message
 161
 162 Features:
 163   --disable-glib           disable glib support [glib support is enabled]
 164
 165 Path options for pkg-config file:
 166   --prefix=PREFIX          install in PREFIX [$prefix_default]

 169
 170 Advanced options (experts only):
 171   --pkg-config-sysroot=SYSROOT if you need to tell pkg-config that you cross-compile
 172   --slib-cc=CC                 use C compiler command line CC for shared lib object[$slib_cc_default]
 173   --slib-ccld=CCLD             use linker command line LD for shared lib [$slib_ccld_default]
