The best you can do with those generators is to create a static library instead of a linked executable.
Good point... So I ended up adding main to all tests... Thank's a lot.In case this interests somebody, I attach my current version of the C++ tests in this mail (this is clearly work in progress, needs some cleaning and some improvement -- such as limiting the number of times it is launched -- but if there are useful comments I'll take them).
Usage: dump the directory under your project, add these lines to your project:
SET(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake")
INCLUDE(CheckCXXFeatures)
CHECK_ALL_CXX_FEATURES(BZ_)
The BZ_ is a prefix to add to all the various variables defined by this
"module".
This is maybe misplaced but allows generated config.h of various project
to not conflict...
