I have installed zlib using apt install zlib1g-dev and also pkg-config. Those install steps are not in the dockerfile(s) shared below.

Steps To Reproduce

git clone -b master TensorRT
cd TensorRT
git submodule update --init --recursive
export TRT_SOURCE=`pwd`

export TRT_RELEASE=`pwd`/TensorRT-

mkdir -p build && cd build
make -j$(nproc)

The above steps are done in a container.

Could you try if the following command helps?

$ sudo apt-get install zlib1g-dev


I already tried that and reported it in the question. But somehow CMAKE is not able to find it looks like.

make sure to run apt install pkg-config rather than building from source. That way there is no need to explicitly install zlib.
