As far as I can tell from cmake documetation

https://cmake.org/cmake/help/v3.9/manual/cmake-variables.7.html

CMAKE_RUNTIME_OUTPUT_DIRECTORY is under the section "Variables that Control the Build". I take that to mean it is meant to be set and not read. That would also correspond with the fact that it gives me an empty path when I initialize P4_BINARY_DIR with it.

Under "Variables that Provide Information" section there is:

CMAKE_CURRENT_BINARY_DIR gives me /home/mvo/kde/build/extragear/kdevelop/kdevelop/plugins/perforce/tests (The executable is under /home/mvo/kde/build/extragear/kdevelop/kdevelop/plugins/perforce/p4clientstub and at a different relative location under windows)
<PROJECT-NAME>_BINARY_DIR gives me /home/mvo/kde/build/extragear/kdevelop/kdevelop/
PROJECT_BINARY_DIR gives me /home/mvo/kde/build/extragear/kdevelop/kdevelop/ (because there is only one project declaration in all of kdevelop)

I'm not a big fan of scanning the entire build dir either. but at least it is only done once pr. testrun
