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

use target name instead of the resulting library, use more macros around

merge cmake_pascal branch in default

actually tests are there to be tested, just skip the variable assignment on windows

Backed out changeset c4289023ddae

don't run the broken windows test at all on windows

gather up the linker flags in a macro

bring windows fixes from main repo

another code typo

apply linker flags to all relevant targets

explicitly set the origin linker flag so that $ORIGIN is used correctly

add a possible lua include path

less cached cmake output

code typos

use QT_DEBUG which is always added

respect C and CXX flags

freepascal on windows only supports shared libraries

nitpick

heavily rework lua discovery and linking, needs testing but it's more similar to what we do for other libraries now

oops, haskell uses gcc to link, correctly pass flags

since shared libs are now our friends, let's optimise them
