/usr/bin/php: PHP8.3（APTで入れたもの） -
/opt/php8.4/bin/php: PHP8.4 RC1（ソースからビルドしたもの）
という2バージョンが共存しているマシンで、PHP8.4 RC1向けにXdebugをビルドしたかった。
8.4のphpizeを使えば行けるのかと思ったらそうではなかったのでメモ。
普通にphpize+./configureしたときのログ

↓のあたりのログから、/opt/php8.4のPHPを見てくれていないことがわかる。
checking for PHP prefix... /usr
checking for PHP includes... -I/usr/include/php/20230831 -I/usr/include/php/20230831/main -I/usr/include/php/20230831/TSRM -I/usr/include/php/20230831/Zend -I/usr/include/php/20230831/ext -I/usr/include/php/20230831/ext/date/lib
checking for PHP extension directory... /usr/lib/php/20230831
checking for PHP installed headers prefix... /usr/include/php/20230831
これを変更するには、./configureに--with-php-config=/opt/php8.4/bin/php-configを渡せばよい。
php-configはPHPのバイナリやライブラリがインストールされている各種パスを返してくれるコマンド。
./configureは--with-php-configでの指定がなければ$PATHからphp-configを探すため、8.3の/usr/bin/php-configを使ってしまう。
