Help with catch2 transition needed

[Andreas Tille <andreas@an3as.eu>]

Hi,

as per bug #1054707 libodsstream failed to build from source due to

 /<<PKGBUILDDIR>>/test/test_ods.cpp:3:10: fatal error: catch2/catch.hpp: No such file or directory
     3 | #include <catch2/catch.hpp>
       |          ^~~~~~~~~~~~~~~~~~
 compilation terminated.

I noticed that catch2 does not contain the header file catch.hpp any
more.  There is now some catch_all.hpp.  So I replaced this header file
in a patch[1] but obviously this problem can't be solved by pure wild
guessing since this has lead to 

   /usr/bin/ld: /usr/lib/gcc/x86_64-linux-gnu/13/../../../x86_64-linux-gnu/Scrt1.o: in function `_start':
    (.text+0x17): undefined reference to `main'

and my manually added main() function (also in patch[2]) did not
enhanced the situation much since its now running into linker errors[2].

Any hint how to fix this catch2 issue properly would be welcome
     Andreas.
