I can help. The reason for the build errors is due to running cmake inside the benchmark directory - that's why it can't find the coz-instrumentation
target.
The answer is to configure from the root directory using the main CMakeLists like this:
cmake -B build -DBUILD_BENCHMARKS=on -DCMAKE_BUILD_TYPE=Debug
cd build
make
That will make the lib and all the benchmark targets.

I am getting exactly the same error message saying
"cannot find -lcoz-instrumentation"
Anyone can help?

@chadbrewbaker checking out the repo at this state works fine: https://github.com/plasma-umass/coz/tree/c9af2bcc172ee4af66082c1ea9ae75a19d2cd0f6

That's useful information! I will look into this.

@chadbrewbaker I managed to fully build & successfully an older version of coz:
Steps:
1. I'm using Linux Ubuntu Server 20.04 (Focal Fossa): https://cloud-images.ubuntu.com/focal/ (created a VM from scratch)
2. Followed the instructions from https://github.com/plasma-umass/coz/tree/381cbe57f2b47e8a8ca8a010978a09343246a4ec => but after checking out the repo and doing cd coz, I did a 'git checkout 381cbe5' to be in this exact state
3. Did make to compile coz
4. Added libcoz to PATH
After these instructions, I was able to make bench and run coz commands on a particular program and get a valid profile.coz :).
@emeryberger newer versions of the repo don't seem to work out of the box (i.e. having a simple program e.g. toy to be "profile-able") - maybe is a problem with newer versions of Ubuntu.
#107 this conversation also helped.
