Unable to specify/add php modules for the "cli" #1157

Hi, i am working to port a php application in my Cloudfoundry, using :

buildpack: https://github.com/cloudfoundry/php-buildpack/releases/download/v4.6.26/php-buildpack-cflinuxfs4-v4.6.26.zip stack: cflinuxfs4

the compose.json requires "fileinfo" and "gd" and even if the modules are specified as per documentation:

.bp-config/php/php.ini.d/custom.ini

extension=mysqli.so extension=redis.so extension=curl.so extension=gd.so extension=xsl.so extension=mbstring.so extension=soap.so extension=openssl.so extension=fileinfo.so extension=imagick.so zend_extension=opcache.so

if i check the extension via browser (so using the stack apache -> phpfpm) i can see the extensions, but those are not loaded in the CLI so the composer install always fails.

any chances i can specifiy php extension in the CLI during build?
