configure: error: Package requirements (xcb-renderutil) were not met:

Package xcb-renderutil was not found in the pkg-config search path.
Perhaps you should add the directory containing `xcb-renderutil.pc'
to the PKG_CONFIG_PATH environment variable
Package 'xcb-renderutil', required by 'world', not found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables XCB_RENDERUTIL_CFLAGS
and XCB_RENDERUTIL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
