QT5.8 -static -static-runtime needs VisualStudio Runtime

Hi,
I tried to compile QT5.8 statically by using MSVC++2015. After compiling the standard dynamic version I tried a -static version using a dynamic runtime library and then a static runtime.

Source code

configure -prefix /testqt5.8dynRT  -static   -opengl desktop -no-openssl   -opensource  -confirm-license    -skip qtwebkit   -release 

configure -prefix /testqt5.8statRT  -static -static-runtime  -opengl desktop -no-openssl   -opensource  -confirm-license    -skip qtwebkit   -release 

To compile my program I had to switch from \MD to \MT and the executable files became bigger. BUT that was the only difference. Both still needed the runtime DLLs although I used " -static -static-runtime" as a parameter in the second case.
And it clearly had an influence. Otherwise I would not have been forced to switch to \MT.

P.S.: An other odd occasion was the fact that compiling "static -static-runtime" was relatively fast. Later "jom install" made several calls to cl.exe. I always thought that everything is done after the make and "make install" just copies the files?

Edit: Someone called Krishty alluded to me in a German board to deactivate "Link Library Dependencies". It worked, but why. Is that similar to /MT just affecting the libraries?
