cmake.cacheInit does not respect absolute paths in environment variables

[Atry]

Brief Issue Summary

Reproducing steps

1. Set environment variable CMAKE_INIT_CACHE to an absolute path, e.g. /tmp/my-init-cache.cmake
2. Add the following setting in settings.json

   "cmake.cacheInit": "${env:CMAKE_INIT_CACHE}"

3. Click "Configure All Projects" button

I expect the file /tmp/my-init-cache.cmake will be used to initialize CMake cache. Unfortunately the following command is invoked:

cmake ... -C /home/my-user/my-workspace//tmp/my-init-cache.cmake ...

[elahehrashedi]

it looks like we are not expanding the path before we test if it is an absolute path.

Can you try using this setting and see if it works:
"cmake.cacheInit": "/tmp/my-init-cache.cmake"

The following setting works:

"cmake.cacheInit": "/tmp/my-init-cache.cmake"

Workaround:

"cmake.cacheInit": "/${env:CMAKE_INIT_CACHE}"

then the following command will be executed:

cmake ... -C //tmp/my-init-cache.cmake ...
