Problem building w/ mimalloc on Linux

[sotlampr]

I have a problem building the latest version on Ubuntu 24.04 / CMake 3.28.3:

[ 47%] Built target mimalloc_external                                                                                               
cvutil/CMakeFiles/cvutil.dir/build.make:243: *** target pattern contains no '%'.  Stop.                                             
gmake[1]: *** [CMakeFiles/Makefile2:125: cvutil/CMakeFiles/cvutil.dir/all] Error 2                                                  
gmake: *** [Makefile:156: all] Error 2     

The offending line in the makefile is:

cvutil/libcvutil.so.2.5.0: $$<$$<PLATFORM_ID:Windows>:/home/sot/src/cvutil/build/_external/mimalloc/install/bin/mimalloc.dll>       ~ 

FYI I built it manually and noticed these additional issues:

• libmimalloc.so does not get installed
• libcvutil.so does not link correctly with libmimalloc
• I got some undefined references regarding the C++ stdlib when trying to use libmimalloc

Thanks!
