it would be desirable for full cross-platform scripting of bigger cmake-projects to be able to run cmake scripts (cmake -P <script file>).

This is not possible at the moment as the plugin fails the build if it doesn't find a CMakeCache,txt, so even though the script file specified with a -P command-line option runs properly, the build will always fail.

Even though it would be possible to launch cmake via a shell command, this is not desirable as it requires cmake to be in the PATH of the build slave, creating conflicts as soon as multiple cmake installation are present. I believe it would be advantageous if the CMake tool configuration could be reused for this.
