#.rst:
# CheckFortranSourceCompiles
# --------------------------
#
# 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.
# Will be created as an internal cache variable.
# ``<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
