Requires LibMariaDB

[GWRon]

When doing a "broadband" module build via "MaxIDE - Build Modules" you will end up with this:

Package libmariadb was not found in the pkg-config search path.
Perhaps you should add the directory containing `libmariadb.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libmariadb' found

if you do not have mariadb-stuff installed.

Such things might affect other modules too: stuff which is "convenient to have" but requiring "extra installation". Dunno how to tackle such things conveniently. Telling "bmk" what a module requires on external libs and this then reporting to the user in the sense of "I skipped compiling it because..." ?
