Ok first thing: I had two cmakes on my system, one was 2.8.1, and an older
2.6.3 that snuck in through an incorrect script of mine.
Second thing: the TARGET_FILE thing works. But the usual add_test(name
command) does not.
Ok here we go, minimal test case is attached (uses cmake 2.8.1),
procedure:
save all files into /tmp/test
mkdir /tmp/build
cd /tmp/build
cmake ../test/ && make VERBOSE=1 check
results of that are attached as result.txt
thanks
