Updated patch a bit. Now steps are the same:

     $ cmake -S . -B build
     $ cmake --build build
     $ cmake --build --target LuaJIT-test

ctest and test target works too.

Updated labels, now labels are equals to prefix of appropriate testsuite.

This option is already used by test targets, see TEST_FLAGS in 
test/CMakeLists.txt.

If you run tests by ctest then you should set env variable 
CTEST_OUTPUT_ON_FAILURE=1.

Another option is setting default ctest options via 
CMAKE_CTEST_ARGUMENTS, but it is available since CMake 3.17.

No, it doesn't break integration. Letter with patch has  a link to PR to 
tarantool repository,

all CI tests are passed.

The patch replaces prove with ctest. Updating test runner for PUC Rio 
Lua and LuaJIT testsuites

is out of scope for this patch. This could be done later and by someone 
else.
