roottest-cling-parsing-semicolon is not running, because semicolon is special in cmake?

I did not manage at first to run the semicolon test, since it just didn't exist in my local build. After I changed the name to semicollon, I could run the test (with its new name). I did not see the test mentioned in the one CI log I looked at, so I am wondering if anyone else is able to run this test?

(I have no clue how we manage run this test in our nightlies, maybe depends on the cmake version).

The semicolon in the MACROARG is also not working to be properly passed forward.

Reproducer

ctest -R semicolon

ROOT version

master

Installation method

from source

Operating system

linux

Additional context

cmake --version
cmake version 3.26.5

Random guess: did you try escaping the semicolon abc\;xyz?

Or using $<SEMICOLON> see https://cmake.org/cmake/help/v3.7/manual/cmake-generator-expressions.7.html

I acknowledge the problem. What is rather surprising, is that the name semicolon is enough for ctest not to find the test. Even thesemicolon works.

Yes I tried both of these. I also tried 2, 3, 4 and 8 (or something) slashes. With enough slashes the semicolon turns into a space. At that point I gave up

once the test runs, as correctly pointed out, fails. I did not find yet the right way to feed the correctly the string with ";"
