CMake integration doesnt' work

[Steve132]

The merge to integrate cmake tools at

#51

Is a really cool addition that I (as a CMake user) desperately want.
however, it doesn't work.

The reason it doesn't work is because

https://github.com/harikrishnan94/cxx-compiler-explorer/blob/cb8d03d9e395c5bf1863ce5e6b1baeee7bec85c6/src/compdb.ts#L76C1-L76C82

tries to load the empty file, but fails when the file isn't there. This SHOULD trigger an exception which is caught by the except block, initializing the map with an empty map in the exception handler case...but for some reason its not. The exception passes through to the VsCode editor. Probably, ENOENT exceptions inside await blocks aren't caught by exception handlers? Or something? It seems unclear.

This issue means I can't use the CMake support.
