[CMake] using TRY_COMPILE() for testing

[Frank Stappers]

Hi,

I wanted to know if it whether it is possible to use TRY_COMPILE() in
a ADD_TEST(), such
that the results can be uploaded to a CDash server.
Currently, when executing cmake for the project all TRY_COMPILE()
statements are executed and
evaluated at configure time. This takes some time as there are roughly
600 TRY_COMPILES() executed,
which are project dependent.
So, I had the idea to do the following in a CMakeLists.txt:

add_test( foo  try_compile( result bindir foo.cpp ...  ) )

such that each of the test are executed when calling "ctest" Unfortunately,
this does not work, since "try_compile(...)" is not an executable. So my
guess is that I have to do something more advance.

So my question is what should be the "easiest" way to achieve this
kind of behavior?

KR,
