In porting a library (blitz) from autoconf to cmake, I have the
sub-project of testing C++ compiler features.
The autoconf way was to create some C++ files and test that they are
compiling (and just compiling not linking).
TRY_COMPILE (in the variant that creates automatically the CMake
project) seems to oblige me to link the code.
Many of the tests (taken from autoconf) do not include a main(), some
the tests fail. Obviously, I can create a main,
but I wondered if there was an easy way to avoid the linking phase
(without having to create my own CMake project
for all those files).
Thank's in advance,
Theo.
