BUG: MacOS support libraries end up into `res://build/*`

[clemens-tolboom]

After #33 lands we still face:

The MacOS build process results in the supporting files into res://build/ directory.

Fiddling removing /build makes them required in res:// aka the root of the demo project. Which is worse.

We do not understand this dynamics on MacOS. Help needed.

Making the link arguments more explicit we are building into the Godot dir but grab the sub libraries from the src/*/build/

g++
  -o demo/addons/geodot/osx/libgeodot.dylib <========== into demo

  -arch x86_64
  -dynamiclib
  src/gdlibrary.os
  src/geodata.os
  src/geodot.os
  src/geofeatures.os src/geoimage.os

  -Lgodot-cpp/bin <================ why is this behaving 'normal' ?
  -Lsrc/raster-tile-extractor/build <====== causing trouble
  -Lsrc/vector-extractor/build  <====== causing trouble
  -L/usr/local/Cellar/gdal/3.2.1/lib <==== System required

  -lgodot-cpp.osx.release.64
  -lRasterTileExtractor
  -lVectorExtractor
  -lgdal

So what would happen when building local then copy into demo/**?

Some more info about dynlib

otool -L /usr/local/Cellar/gdal/3.2.1/lib/libgdal.dylib

and

otool -L demo/addons/geodot/osx/libgeodot.dylib

We can run the same on Godot

[clemens-tolboom]

So in short

otool /Applications/Godot_v3.2.4-rc1_osx.universal.app/Contents/MacOS/Godot -L

helps a little for understanding and

otool demo/addons/geodot/osx/libgeodot.dylib -L
otool demo/build/libVectorExtractor.dylib 
otool demo/build/libVectorExtractor.dylib  -L
otool /usr/local/opt/gdal/lib/libgdal.dylib -L

shows ways to fix stuff hopefully.

[clemens-tolboom]

Remarks

otool -L demo/addons/geodot/osx/libgeodot.dylib
demo/addons/geodot/osx/libgeodot.dylib

this is the wrong answer as it probably should be relative to the project root /addons

cd demo/addons/geodot/osx
install_name_tool -change demo/addons/geodot/osx/libgeodot.dylib  "addons/geodot/osx/libgeodot.dylib" libgeodot.dylib

This is not working ... it should be in an application context I guess?

Export game

If I export the game to MacOS App we get (too few files but what can we do here)

find ./Demo.app -type f
./Demo.app/Contents/MacOS/Demo
./Demo.app/Contents/Resources/icon.icns
./Demo.app/Contents/Resources/Demo.pck
./Demo.app/Contents/Frameworks/libgeodot.dylib
./Demo.app/Contents/Frameworks/libRasterTileExtractor.dylib
./Demo.app/Contents/Info.plist
./Demo.app/Contents/PkgInfo

Check path

otool -L ./Demo.app/Contents/Frameworks/libgeodot.dylib
./Demo.app/Contents/Frameworks/libgeodot.dylib:
	demo/addons/geodot/osx/libgeodot.dylib (compatibility version 0.0.0, current version 0.0.0)
...

Change path

Invalidates signature so that is not how should be done

install_name_tool -change demo/addons/geodot/osx/libgeodot.dylib  "@executable_path/../Frameworkslibgeodot.dylib" Demo.app/Contents/MacOS/Demo

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/install_name_tool: warning: changes being made to the file will invalidate the code signature in: Demo.app/Contents/MacOS/Demo (for architecture arm64)

Recheck path

Name is not changed ... arg

otool -L ./Demo.app/Contents/Frameworks/libgeodot.dylib
./Demo.app/Contents/Frameworks/libgeodot.dylib:
	demo/addons/geodot/osx/libgeodot.dylib (compatibility version 0.0.0, current version 0.0.0)
...

ARM64?

Demo.app/Contents/MacOS/Demo (for architecture arm64)

Wot?!?
