# FindLibGcrypt
|
|
# -------------
|
|
#
|
|
# Try to find libgcrypt.
|
|
#
|
|
# This will define the following variables:
|
|
#
|
|
# ``LibGcrypt_FOUND``
|
|
# True if libgcrypt is available.
|
|
#
|
|
# ``LibGcrypt_VERSION``
|
|
# The version of LibGcrypt
|
|
#
|
|
# ``LibGcrypt_INCLUDE_DIRS``
|
|
# This should be passed to target_include_directories() if
|
|
# the target is not used for linking
|
|
#
|
|
# ``LibGcrypt_LIBRARIES``
|
|
# This can be passed to target_link_libraries() instead of
|
|
# the ``LibGcrypt::LibGcrypt`` target
|
|
#
|
|
# If ``LibGcrypt_FOUND`` is TRUE, the following imported target
|
|
# will be available:
|
|
#
|
|
# ``LibGcrypt::LibGcrypt``
|
|
# The libgcrypt library
|
|
#
|
|
# Since 1.9.50.
