# Check if given Fortran source compiles and links into an executable::

|
#
|
||||||
|
# CHECK_Fortran_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>])
|
||||||
|
#
|

|
# The arguments are:
|

|
#
|

|
# ``<code>``
|
||||||
|
# Source code to try to compile. It must define a PROGRAM entry point.
|
||||||
|
# ``<var>``
|
||||||
|
# Variable to store whether the source code compiled.
|
||||||
|
# ``<fail-regex>``
|
||||||
|
# Fail if test output matches this regex.
|
||||||
|
#
|
||||||
|
# The following variables may be set before calling this macro to modify
|
||||||
|
# the way the check is run::
|
||||||
|
#
|
||||||
|
# CMAKE_REQUIRED_FLAGS = string of compile command line flags
|
||||||
|
# CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar)
|
||||||
|
# CMAKE_REQUIRED_INCLUDES = list of include directories
|
||||||
|
# CMAKE_REQUIRED_LIBRARIES = list of libraries to link
|
||||||
|
# CMAKE_REQUIRED_QUIET = execute quietly without messages
