make sure `pkg-config pangocairo --cflags --libs` prints something, otherwise some -dev packages should be installed given your distribution
package main
// #cgo pkg-config: pangocairo
// #include <pango/pangocairo.h>
// void draw(const char *font, const char *text, const char *output) {
// int width, height;
// PangoFontDescription *font_description = pango_font_description_from_string(font);
// {
// cairo_surface_t *cairo_surface = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, 0, 0);
// cairo_t *cr = cairo_create(cairo_surface);
