# CMake module to search for PDAL library

|

# If it's found it sets PDAL_FOUND to TRUE
|

|

# PDAL_LIBRARIES
|
|
|
|
# FIND_PATH and FIND_LIBRARY normally search standard locations
|
|
# before the specified paths. To search non-standard paths first,
|
|
# FIND_* is invoked first with specified paths and NO_DEFAULT_PATH
|
|
# and then again with no specified paths to search the default
|
|
# locations. When an earlier FIND_* succeeds, subsequent FIND_*s
|
|
# searching for the same item do nothing.
