Can not determine project directory

[buraksenkus]

Hi sir, I'm facing a problem when I'm trying to enable WITH_SIMULTE option.

First of all, here are my steps:

• I configured and ran make Omnet++ 5.6.2.
• I ran make inet, make vanetza, make simulte and cd extern/veins && ./configure && make in order. These steps have been completed successfully.
• Then I ran cmake .. in OpenCV2X/build directory. Its output was like below.

After that, I tried to enable **WITH_SIMULTE** option. But when I set it and try to run cmake again it gives below error.

I could not understand the problem exactly. Thanks for your help in advance!

I have solved the problem. Let me briefly summarize the situation in case others may experience the same problem again. Some time ago I cloned and built the repository on a different computer. I rebuilt over the files that currently exist on a different computer. As far as I understand it, the directories of some files were saved statically during the previous build process and that was the point that led to the problem. The problem disappeared when I cloned the repository from scratch and did the make steps cleanly. Since have I solved the problem, I'm closing the issue.
