[fpc-pascal] PMake a new build tool

[Darius Blaszyk]

Hi Silvio,

I've looked for something like this to automate the build of some projects

By executing 'pmake --compiler <delphi-compiler-path>', it should be easily
possible to build Delphi projects (I don't have Delphi so I cannot test).
The compiler path will be stored in the PMakeLists.txt cache (in the
$(PMAKE_PAS_COMPILER) variable) and used every time again for the build. It
should also be possible to use different compilers by setting the
$(PMAKE_PAS_COMPILER) variable in the PMake script. PMake allows for option
variables to be set in PMake.txt (at any level). See also the PMake project:

option('WITH_DEBUG', 'Enable debug info for PMake', _ON_);

I believe you should use add_custom_command for this. It will create a
package for you that you can add as dependency to a library or executable.
Only after the dependency is resolved, the remaining build will continue.
If you test and have an example, please make a pull request so it can be
added for prosperity.

The nice thing about PMake is that it also works when pulling together two
different projects using PMake. You only need to use add_directory (and the
correct dependencies of course) to get get a working build.
