# Use this module by invoking find_package with the form:
5+
# find_package(ADIOS
6+
# [version] [EXACT] # Minimum or EXACT version, e.g. 1.6.0
7+
# [REQUIRED] # Fail with an error if ADIOS or a required
8+
# # component is not found

# [QUIET] # ...
10+
# [COMPONENTS <...>] # Compiled in components, ignored
11+
# )
12+
#
13+
# Module that finds the includes and libraries for a working ADIOS install.
14+
# This module invokes the `adios_config` script that should be installed with
15+
# the other ADIOS tools.
16+
#
17+
# To provide a hint to the module where to find the ADIOS installation,
18+
# set the ADIOS_ROOT environment variable.
19+
#
20+
# If this variable is not set, make sure that at least the according `bin/`
21+
# directory of ADIOS is in your PATH environment variable.
22+
#
23+
# Set the following CMake variables BEFORE calling find_packages to
24+
# influence this module:
25+
# ADIOS_USE_STATIC_LIBS - Set to ON to force the use of static
26+
# libraries. Default: OFF
27+
#
28+
# This module will define the following variables:
29+
# ADIOS_INCLUDE_DIRS - Include directories for the ADIOS headers.
30+
# ADIOS_LIBRARIES - ADIOS libraries.
31+
# ADIOS_FOUND - TRUE if FindADIOS found a working install
32+
# ADIOS_VERSION - Version in format Major.Minor.Patch
33+
#
34+
# Not used for now:
35+
# ADIOS_DEFINITIONS - Compiler definitions you should add with
36+
# add_definitions(${ADIOS_DEFINITIONS})
