Issue description:

On MacOS gdexample.gdextension doesn't point to correct library:

ERROR: Can't open dynamic library: /Users/jpedrick/Development/godot-master-cpp-tutorial/cpp-tutorial/demo/bin/libgdexample.macos.framework, error: dlopen(/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework, 0x0002): tried: '/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework' (no such file), '/Users/jpedrick/Development/godot.git/bin/../Frameworks/libgdexample.macos.framework' (no such file).

Two fixes are needed:

1) scons platform=macos => scons platform=macos target=editor 2) gdexample.gdextension =>

[configuration]

entry_symbol = "example_library_init"

[libraries]

linux.64="res://bin/libgdexample.linux.64.so"
windows.x86_64="res://bin/libgdexample.windows.x86_64.dll"
macos="res://bin/libgdexample.macos.editor.framework/libgdexample.macos.editor"

Which godot-cpp commit do you use? Also, does this only occur for editor builds or also for debug builds? My tests for the docs were mainly built on the debug build which only entailed the .framework/ folder for MacOS and worked with only this part

Hi @paddy-exe , I used the 4.0 release as well as:

commit feaba551b5a5b2d13ad1c3fdd8c90e67c67ff37c

The key problem is that shared library is in a directory.
