Cmake failure, sndfile missing, maint-3.9 (Ubuntu 20.04)

[LightningBolt216]

Having trouble getting the maint-3.9 version to work with GNU Radio 3.9.5. Need this version for to get the CSI information. GNU Radio was installed through apt-get (PPA). Seems like it is having trouble locating a library called sndfile. See output below.

Specifics:
OS: Ubuntu 20.04.1
Kernal: 5.13
GNURadio Version: 3.9.5.0 (Python 3.8.10)
CMake version: 3.16.3
gr-ieee802-11 version: maint-3.9

Cmake output:
