Fix CaDiCaL auto-download on macOS (#6828)
* Fix CaDiCaL auto-download on macOS
If we are auto-downloading CaDiCaL, we are manually instantiating its makefile.
To do that, we use `CMAKE_CXX_COMPILER` for the compiler and assemble some
flags. However, we are missing the platform dependent flags. Specifically, we
need to set `-isysroot` on macOS to make sure that the header files are found
because they are not at /usr/include on newer versions of Apple's XCode [0].
Unfortunately, I could not find a CMake variable with the platform specific
flags. They are assembled here [1]. To solve this problem, the commit checks if
`CMAKE_OSX_SYSROOT` is set and adds a corresponding compiler flag if it is.
