How do you clone the repo? Download from GitHub or do git clone?
@s3rj1k I suspect ${CHANGELOG} is empty at line 168 string(REPLACE "\"" "" CHANGELOG ${CHANGELOG})
https://github.com/signalwire/signalwire-c/blob/master/CMakeLists.txt#L168

[andywolk]

Ohh. I missed the fact that the answer is in the log. You clone with git.
@s3rj1k Do you have an idea what's wrong?

[evandrocoan]

I fixed it by changing month to year:

signalwire-c/CMakeLists.txt

Line 164 in 14324c9

execute_process(COMMAND ${GIT_EXECUTABLE} log --no-merges --pretty=format:"%n [%an]%n * %s" --since="last month"

There were no commits on the last month, then, the value of the variable is empty.

Why are you doing this? The change from month to year will not fix it forever, i.e., on the next year, if not commits come, this will crash again.
