Change Make variable syntax to use curly braces most of the time - #294
Merged
Conversation
Wherever possible, change the Make variable syntax to use curly braces
(`${VAR}`) instead of parentheses (`$(VAR)`) to ease code portability
between Makefiles and Bash scripts.
We will continue using parentheses for Make functions such as:
- `$(abspath …)`
- `$(patsubst …)`
- `$(shell …)`
- `$(subst …)`
- `$(wildcard …)`
- Etc.
and for Make variables that would mean something different in Bash or
would not work there at all, such as:
- `$(*:.in=.txt)`
- `$(*)`
- Etc.
