issue #672, frontend less spammy

This commit changes many aspect of our cmake build system - shared libraries are compiled by default: * this modifies RPATH of unix executables; * this will prevent a lot of linking issues, esp. from pascal world; * the old behaviour (static libs) is still available with -DBUILD_SHARED_LIBS=off; * of course in this case you have to provide the full list of dependencies with FPFLAGS and CMAKE_C_FLAGS; - pascal is now fully integrated with cmake, meaning you can just do add_sources and use CMAKE_Pascal_FLAGS: * some of the language features are only partially implemented, for example .inc files will not get rebuilt if you modify them; * target_link_libraries for pascal targets is just dummy as linking is determined within pascal files; * universal builds for osx are not available any more; - bundled libraries and system libraries are addressed using the target name: * this avoids depedency tracking; * this allows to name output as we wish.

when you don't use bundled dirs, add a fake target anyway, so you can use the same cmake syntax even if the target uses a different name

there is no need of escaping after all...

this should fix rpath problem

oops, forgot to set the path after all

less spam

remove two unused cmake files

this should resolve a few issues on clean builds

oops, use right macro name
