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...
