Cannot open uci.h

Hi I am trying to use UCI in amy application but the compiler cannot find the uci.h file
following is my code


#include <uci.h>
#include <stdio.h>

int main() {
	uci_context* ctx = uci_alloc_context();

	if (!ctx) {
		printf("failed to alloc uci ctx\n");
		return 1;
	}

	uci_ptr config;
	char section_name[] = "your_package.your_section";

	if (uci_lookup_ptr(ctx, &config, section_name, true) != UCI_OK || !config.s) {
		printf("failed to find the specified section\n");
		return 1;
	}

	config.option = "new_option_name";
	config.value = "new_option_value";

	if (uci_set(ctx, &config) != UCI_OK) {
		printf("failed to set new option\n");
		return 1;
	}

	if (uci_commit(ctx, &config.p, false) != UCI_OK) {
		printf("failed to commit changes\n");
		return 1;
	}

	return 0;
}

Help would be appriciated,
