libosmovty version is UNKNOWN

Hello, Unfortunately I have come up to the problem that I can't google myself and my friends can't help with either. Maybe it has something to do with readme saying that libsomocore in the git I pulled isn't for system wide installation but when I make the osmocombb src then it spits out this: configure: error: Package requirements (libosmovty >= 0.10.0) were not met: Requested 'libosmovty >= 0.10.0' but version of Osmocom VTY Interface Library is UNKNOWN Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBOSMOVTY_CFLAGS and LIBOSMOVTY_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. Makefile:94: recipe for target 'host/layer23/Makefile' failed make: *** [host/layer23/Makefile] Error 1 If I need to get a different libosmocore could you provide it to me? Thank you
