I got an error while compiling PHP, I am listing the details below.

```
Error configure error libxpm.(a so) not found

```

I have checked with dpkg -L libxpm-dev. it is showing the needed file is in the folder 
`/usr/lib/x86_64-linux-gnu/`(libXpm.a).

I have tried with `--with-xpm-dir=/usr/lib/x86_64-linux-gnu`, but error still exists.
