Describe your environment

I have a number of projects which, for various reasons, are not currently included in the program which runs the unit tests. It would be very useful if I could nevertheless get a line count from those projects so that I could get a better view of my overall coverage. So if I had two projects Xprj and Yprj, each with one file in each (X.xpp and Y.cpp), each with 100 lines of code, and my test program only tested Xprj, I would like to know that I was only 50% covered, not 100% covered, even if this was done after the coverage program had run.
I can of course calculate a line count myself, but it would be useful if this was done in the same way as the coverage calculates it.
So ideally I would like a separate program that I could point out Xprj and Yprj together to give 200 as the total line count. Thanks

Hello,

You are not the first one to have this use case so I will try to provide a way to do it! Does it help if OpenCppCoverage will have a way to include another project with the PDB file (--extra_pdg=MyProject2.pdb)?

Note: You need to be a little patient: https://github.com/OpenCppCoverage/OpenCppCoverage/issues/72

I'm not too fussed how I get there, so adding extra PDBs to the command line would probably be fine. Perhaps even good - it would mean that one run would get all the data and I wouldn't have to do anything outside. Thanks.
