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

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

The arguments are:


Source code to try to compile. It must define a PROGRAM entry point.


Variable to store whether the source code compiled. Will be created as an internal cache variable.


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
