Support CTest without CMake

[kalvdans]

We have a Python project with no compiled code, and no need for cmake. But we still like to use ctest as the test driver. It works find from the command-line, and have the list of tests in CTestTestfile.cmake (as documented).

In order to get them into vscode test explorer, two hacks are needed to trick cmake-test-explorer to believe the source directory is a build directory:

• Create a CMakeCache.txt with a single line: CMAKE_CTEST_COMMAND:INTERNAL=ctest
• Change configuration: "cmakeExplorer.buildDir": "."

Would it be possible to make vscode-cmake-tools discover a testable directory by the existance of CTestTestfile.cmake?

@kalvdans This sounds like a feature request, could you create an issue on the Issues pane so that we can properly track this? Thanks!
