# Findgbm
|

# -------
|
|
#
|
|
# Try to find gbm on a Unix system.
|
|
#
|
|
# This will define the following variables:
|
|
#
|
|
# ``gbm_FOUND``
|
|
# True if (the requested version of) gbm is available
|
|
# ``gbm_VERSION``
|
|
# The version of gbm
|
|
# ``gbm_LIBRARIES``
|
|
# This can be passed to target_link_libraries() instead of the ``gbm::gbm``
|
|
# target
|
|
# ``gbm_INCLUDE_DIRS``
|
|
# This should be passed to target_include_directories() if the target is not
|
|
# used for linking
|
|
# ``gbm_DEFINITIONS``
|
|
# This should be passed to target_compile_options() if the target is not
|
|
# used for linking
|
|
#
|
|
# If ``gbm_FOUND`` is TRUE, it will also define the following imported target:
|
|
#
|
|
# ``gbm::gbm``
|
|
# The gbm library
|
|
#
|
|
# In general we recommend using the imported target, as it is easier to use.
|
|
# Bear in mind, however, that if the target is in the link interface of an
|
|
# exported library, it must be made available by the package config file.
