# fails to run. Action-if-found is evaluated if the application

# runs successfully (or compiles if cross-compiling), and
|

|
# action-if-not-found is evaluated if the application fails to
|
||
|
|
# run.
|
||
|
|
#
|

|
|
# language-exit should be how to exit cleanly in 'language'.
|
||
|
|
# You probably want exit(0) for C/C++ and empty for Fortran.

|
