Summary:                    Command line definitions ignored if
-DCMAKE_C_COMPILER is passed
Description: 

In the Qt 5 unit tests, we pass the compilers at each test run to workaround
broken configuration in the CI system:

 https://bugreports.qt-project.org/browse/QTQAINFRA-609

However, this means that at each invocation after the first, command line
content is not processed:

$ cmake .. -DTESTVAR=True -DCMAKE_C_COMPILER=gcc
TESTVAR = True
-- Configuring done
You have changed variables that require your cache to be deleted.
Configure will be re-run and you may have to reset some variables.
The following variables have changed:
CMAKE_C_COMPILER= gcc

-- The C compiler identification is GNU 4.7.3
-- The CXX compiler identification is GNU 4.7.3
-- Check for working C compiler: /usr/lib/icecc/bin/gcc

-- Configuring done
