MacOS tool is not working

[Pavel401]

Hi, I have installed all the required dependencies mentioned in the readme file. However, when I run the tool, it shows an error that I am unable to debug. I need some help with this.

error :

I guess the issue cause is HOMEBREW_PREFIX environment (in current CMakeLists.txt) is used for finding ICU library. I will fix this issue when I get my hand on macbook.

You can workaround by export HOMEBREW_PREFIX=$(brew --prefix) and remove build directory. The, run the command again.

In latest commit, it should work without setting HOMEBREW_PREFIX environment.

If an error still occur, try deleting "build" directory first.
