`circle` cannot compile `googletest`.

[Life4gal]

I really like the design of the circle, it gives me an unparalleled experience in programming in C++.

I can't wait to use circle in some of my projects, but currently I'm running into some unavoidable problems. :(

I have a sample repo here that is fully functional (albeit very rudimentary).

Because CLion currently has some hardcoding for cmake to check the CXX compiler and get the compiler information can't be avoided, so I have to use VS+WSL for development. :)

This repository has a bash script, run it before opening the project from VS, it will generate a CMakeSettings.json, VS relies on this file to run the CMake configuration.

Below is my CMake output:

ninja: build stopped: subcommand failed.

It can be seen that googletest will pass many compiler options to circle when compiling, but currently circle does not support them, and then the compilation stops. :(
