Hi Francisco,
for the SDL Framework (downloaded from libsdl.org) you don't need the
bundleUtilities, so don't use it (in fact it doesn't work as you also
found out). If you just don't copy anything, then the app should just
work (assumed, that you SDL Framework is either in /Libraries/Framework
or /Users/user/Libraries/Framework.
Test this. Run the created app. Does it work?
To create an app bundle with framework included, run cmake like that
cmake -DCMAKE_INSTALL_PREFIX=installdir path-to-src
and in CMakeLists.txt add this INSTALL(Directory ..) commands I send you
earlier.
Now when you run "make", an app is created without the Framework. Does
it run? When you do now "make install" an app will be created in
installdir, where the Framework should be included. Does it run? if yes,
copy it to another computer where no SDL is installed and try again.
HTH,
Werner
