Summary0014366: 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
-- Check for working C compiler: /usr/lib/icecc/bin/gcc -- works
-- Detecting C compiler ABI info

-- Check for working CXX compiler: /usr/lib/icecc/bin/c++

 Have you tried using -D along with the full path to the compiler?

(instead of just "gcc"...)

 Yes, that works.
