or is your main top-level CMakeLists.txt the only CMakeLists.txt with
project  command ?

How can I run all tests at once?

make tests ?
ninja tests ?
ctest ?

What does
$ ctest -N
says?

This should work at least it "works-for-me" so there must be some
difference between the CMakeLists.txt in the directory that works and in
the directory that does not.
Do you have a sample setup which exhibit the issue that you can share?


Thank you in advance.
