# - try to find MyPackage library

|
# This module does the same thing as Example-FindMyPackage.cmake
|
||
|
|
# except that rather than passing along full path names for libraries,
|
||
|
|
# it creates imported targets. The end result is roughly the same to
|
||
|
|
# the end-user. Please see that other file for the full documentation
|
||
|
|
# of the example.
|
||
|
|
#
|
||
|
|
# Note that if you're going to be installing target export files, this
|
||
|
|
# is probably what you should prefer. See cmake mailing list archives.
