This is a bunch of small changes that together enable running tests from
CMake with support for QtTest and viewing results in the tool view.
The changes include:
1. Enable listing test cases from tests defined with CMake and QtTest
* Extract sources for each target from cmake server
* Use target sources to look for QtTest declarations in them
* Fix the search for QtTest declarations, so that it works without
access to the main() function body
2. When running tests, parse the output and report results
* Exctract output directly from the OutputModel, which is long-lived,
and not from the shorter-lived OutputJob. The previous method
would lose some lines of output.
* Wait for asynchronous output signals from OutputModel, which again
prevents losing some lines of test program output.
3. A new unit test that checks the cases parsed from source code,
using the existing testing project unit_tests_kde.
With these changes, the test suites and individual test cases appear in the
Unit Tests tool view:
