There is some problem with CMake detecting the mkstemp utility on the macos-latest system.

The following test version of the cmake mkstemp detection scripts find the mkstemp utility:
https://github.com/bradbell/tst_github/blob/main/mkstemp/CMakeLists.txt
Here is the resulting test output
https://github.com/bradbell/tst_github/runs/3525307701?check_suite_focus=true
You will note that this script finds mkstemp because cmake has the following output

-- cxx_has_mkstemp_1 = 1
-- cxx_has_mkstemp_2 = 1

TheCppAD actions branch has a version of the CppAD test that comments out the make check (so it runs much faster than the normail CppAD test):
https://github.com/coin-or/CppAD/blob/actions/.github/workflows/ci_test.yml
The corresponding cmake output can be seen here
https://github.com/coin-or/CppAD/runs/3525397477?check_suite_focus=true
where you will see

 -- cppad_has_mkstemp = 0

I have not been able to figure out why mkstemp is not being detected in this test ?

The fedora package testing if failing on a ppc64le system; see the build.log for
https://koji.fedoraproject.org/koji/taskinfo?taskID=81757910
where the following text appears

to_string           Error
vectorBool          OK
memory_leak         OK
1 tests failed.
End test group example/utility
make[3]: *** [example/utility/CMakeFiles/check_example_utility.dir/build.make:70: example/utility/CMakeFiles/check_example_utility] Error 1

I would like to reproduce this problem using github actions. I tried using
https://github.com/uraimo/run-on-arch-action
to run on a ppc64le arch with the following script
https://github.com/coin-or/CppAD/blob/master/.github/workflows/uraimo_arch_linux.yml

It seemed to hang at the following point:

Build on alpine_latest ppc64le
Started 9h 23m 5s ago
Waiting for a runner to pick up this job...

Does anyone have a suggestion to get this to work, or some other way to reproduce the failure of the Fedora package testing ?
