# Add a new option with default value "auto":
|
||
|
|
# autoOption(FOOBAR "Support foobar")

|
# To check if FOOBAR support should be enabled, use:
|
||
|
|
# if(FOOBAR)
|
||
|
|
#
|
||
|
|
# If necessary dependencies for FOOBAR are missing, use:
|
||
|
|
# autoDisable(FOOBAR "Did not find baz")
|
||
|
|
#
|
||
|
|
# Example:
|
||
|
|
# autoOption(FOOBAR "Support foobar")
|
||
|
|
# if(FOOBAR)
|
||
|
|
# Check for FOOBAR here.

# if(NOT BAZ_FOUND)
