Can't debug cmake msvc application with /MTd flag

CDB debugging not work when project compiled with "/MTd" flag.

For simplicity use simple C++ project without any Qt dependency.

Steps to reproduce:

• Open the CMakeLists.txt in open project dialog (see attachments)
• Select kit with MSVC x86 compiler and CDB debugger (see attached picture)
• Build project with Debug configuration and set some breakpoints
  • for example set breakpoints at:
    • main.cpp:5:   int sum = a + b;
    • main.cpp:14:  int num3 = num2 + sum(10, 90);
• Run in debug mode

Actual result:

The debugger doesn't stop at the breakpoints.

Expected result:

The debugger stops at the breakpoints and can examine/modify variables etc.

If remove/comment out the "set(CMAKE_CXX_FLAGS_DEBUG "/MTd /Od" CACHE INTERNAL "")" from CMakeLists.txt the debugging works fine.
