# - Find ADIOS library, routines for scientific, parallel IO
2
# https://www.olcf.ornl.gov/center-projects/adios/
4
# Use this module by invoking find_package with the form:
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
10
# [COMPONENTS <...>] # Compiled in components: fortran, readonly,
11
# sequential (all are case insentative)
14
# Module that finds the includes and libraries for a working ADIOS install.
15
# This module invokes the `adios_config` script that should be installed with
16
# the other ADIOS tools.
18
# To provide a hint to the module where to find the ADIOS installation,
19
# set the ADIOS_ROOT environment variable.
21
# If this variable is not set, make sure that at least the according `bin/`
22
# directory of ADIOS is in your PATH environment variable.
24
# Set the following CMake variables BEFORE calling find_packages to
25
# influence this module:
26
# ADIOS_USE_STATIC_LIBS - Set to ON to force the use of static
27
# libraries. Default: OFF
29
# This module will define the following variables:
30
# ADIOS_INCLUDE_DIRS - Include directories for the ADIOS headers.
31
# ADIOS_LIBRARIES - ADIOS libraries.
32
# ADIOS_FOUND - TRUE if FindADIOS found a working install
33
# ADIOS_VERSION - Version in format Major.Minor.Patch
36
# ADIOS_DEFINITIONS - Compiler definitions you should add with
37
# add_definitions(${ADIOS_DEFINITIONS})
39
# Example to find ADIOS (default)
42
# include_directories(${ADIOS_INCLUDE_DIRS})
43
# add_executable(foo foo.c)
44
# target_link_libraries(foo ${ADIOS_LIBRARIES})
47
# Example to find ADIOS using component
48
# find_package(ADIOS COMPONENTS fortran)
50
# include_directories(${ADIOS_INCLUDE_DIRS})
51
# add_executable(foo foo.c)
52
# target_link_libraries(foo ${ADIOS_LIBRARIES})
