make install messes up access right in /usr/local

[ysalmon]

Platform

Operating system and version: KUbuntu 20.04
OBS Studio version: 25.0.8 tag from the git repo

Steps to Reproduce

1. run cmake .
2. run make
3. run sudo make install

Expected Behavior

OBS compiled files should be installed and usable in /usr/local

Current Behavior

OBS files are installed but rights to /usr/local are messed up : /usr/local, /usr/local/lib, /usr/local/bin, inter alia, have rights drwxrwx---, even though they existed beforehand with read and execute rights.

Additional information

I checked the root umask and it is 0022.
