About cflags:
Not usable by fpc.

About lflags:
The -l parameters are auto created by the compiler.
This usually leaves none or very few options.

For example $(pkg-config --cflags --libs gtk+-2.0) provides no option
needed by fpc.

About needed libraries:
Because of the above it usually works in FPC the other way
round. You compile and if a library is missing you get an error
message. You then install the missing library and try again.

Nevertheless you are right, it would be nice if you could get the list
of needed libraries without compiling. You can use a
tool like auto-tool for that.
