Subject: [PATCH] + check for vswhere before attempting any detection

+ niceness for terminal output

+ update Windows + Linux scripts to use the new directories of third party + propagate exit error code + fix line ending

+ update Windows deps build script to clean generated build files by cmake after install + propagate exit code of all builds

+ update Linux deps build script to clean generated build files by cmake after install + propagate exit code of all builds

+ fix line ending!
