Compile Kodi /w libcec 4 on updated Ubuntu 16.04

Just tried to update my htpc to latest commit available. Wanted to do this because it includes the libcec 4.
However after the update it does not find the correct package…

When I look in my config.log:

Code:
configure:28227: checking for CEC
configure:28234: $PKG_CONFIG --exists --print-errors "libcec >= 4.0.0"
Package libcec was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcec' found
configure:28237: $? = 1
configure:28251: $PKG_CONFIG --exists --print-errors "libcec >= 4.0.0"
Package libcec was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcec.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcec' found
configure:28254: $? = 1
configure:28268: result: no
No package 'libcec' found
configure:28284: result: == libcec disabled. CEC adapter support will not be available. ==
configure:28365: == libcec disabled. CEC adapter support will not be available. ==

I am 100% sure this package is installed, as well as libcec4, libcec4-dev and libcec-dev

Is there an additional package needed not mentioned in the logs like in it was the case with libcec 3 (where it at that time was mentioned):

Code:
sudo apt-get install libp8-platform-dev
