Sir, this build error is not fixing, I don't know why, kindly look into it.

@Sar-thak-3 pull fresh changes from main and remove the last line in cmake, it's possibly causing build failure

[Sar-thak-3]

Sir, checks were passed, kindly check is it okay?

Revert CMakeLists.txt file and do not change in future PRs

I revert the changes but there is an issue in "src/slowmokit/ducks/matrix/matrix.cpp" , which is creating an error in build.
