Unable to build onetrace on Windows

I am getting following error

Hi, have you tried using the Ninja generator instead? I managed to get it to build with cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release

However, I built w/oneAPI for their OpenCL loader.

oneAPI 2025.0.1 (icx 2025.0.4) VS2022 Professional Edition

Like this:

<oneapi/vcvars>
cd <>/onetrace
mkdir build
cd build
git clone https://github.com/KhronosGroup/OpenCL-Headers.git
cmake .. -DCMAKE_BUILD_TYPE=Release -G Ninja -DOpenCL_INCLUDE_DIR=.\OpenCL-Headers
cmake --build .

Maybe with plain MSVC this will work, but I will need time to try it without the loader. Hitting some path issues building OpenCL-ICD-Loader on Window.s

I will note most of the users of onetrace would probably be better off using unitrace (which is a superset of this functionality).

[MichalMrozek]

Problem with unitrace is that it requires couple of GB of depenencies including whole OneAPI which is not making the build quick. Onetrace doesn't have this problem.

@MichalMrozek, I have sent you an email with engineering build for lighter Unitrace build. Please take a look.

@MichalMrozek You can use BUILD_WITH_* to enable/disable oneAPI dependencies when building unitrace. The ontetrace is considered deprecated.
