[cmake] Glob when copying headers and tutorials

[vgvassilev]

Explain what you would like to see improved and how.

We can copy all the tutorials and header files at once. We do not need to do these operations individually causing things like:

[ 45%] Copying /Users/sftnight/vvassilev/root-src/tutorials/proof/ProofSimple.h
[ 45%] Copying /Users/sftnight/vvassilev/root-src/tutorials/proof/ProofSimpleFile.C
[ 45%] Copying /Users/sftnight/vvassilev/root-src/tutorials/proof/ProofSimpleFile.h
[ 45%] Copying /Users/sftnight/vvassilev/root-src/tutorials/proof/ProofStdVect.C

When using the Makefile Generator that's quite slow for no good reason...
