Summary

0014366: 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
-- Detecting C compiler ABI info - done
-- Check for working CXX compiler: /usr/lib/icecc/bin/c++
-- Check for working CXX compiler: /usr/lib/icecc/bin/c++ -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
TESTVAR =
-- Configuring done
-- Generating done
-- Build files have been written to: /home/stephen/dev/src/playground/cmake/build

CMakeLists.txt:

message("TESTVAR = ${TESTVAR}")
