suggestion about compile.md

Describe you feature request

Is your feature request related to a problem? Please describe.
When I have multiple versions of PHP installed (php7.4, php8.1, php8.3), I execute the run command:

CGO_CFLAGS=$(php-config --includes) CGO_LDFLAGS="$(php-config --ldflags) $(php-config --libs)" go run .

It prompts:

# github.com/dunglas/frankenphp/caddy/frankenphp
/home/circle/go/pkg/mod/golang.org/toolchain@v0.0.1-go1.22.0.linux-amd64/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
/usr/bin/ld: cannot find -lphp
collect2: error: ld returned 1 exit status

Describe the solution you'd like
This error indicates that the ld encountered a problem when trying to link the libphp library. After I changed it to this, the program can run:

CGO_CFLAGS=$(php-config --includes) CGO_LDFLAGS="$(php-config --ldflags) -L/usr/local/php8.3/lib -lphp $(php-config --libs)" go run . run

Should this be written into compile.md?

Start with compile.md and compare its existing run instructions with the reported commands for multiple PHP versions. Document the required PHP library path when php-config cannot resolve libphp, then verify that the documented command matches the working example and lets the project run.
