This is equivalent as `make VERBOSE=1`. Since currently we don't generally use make arguments, it is easier to add to configure procedure.

Without the option, output looks like
```
[ 66%] [ 66%] Building CXX object CMakeFiles/tinyxml.dir/tinyxmlerror.o
Building CXX object CMakeFiles/tinyxml.dir/tinyxml.o
[100%] Building CXX object CMakeFiles/tinyxml.dir/tinyxmlparser.o
Linking CXX shared library libtinyxml.dylib
[100%] Built target tinyxml
```
And with the option:
```
