CMake fix to build cltool on Ubuntu 20.04

[andreucm]

On Ubuntu 20.04, with

$ uname -a
Linux maupas 5.15.0-107-generic #117~20.04.1-Ubuntu SMP Tue Apr 30 10:35:57 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

I have to fix this line on the CMakeLists file, replacing it by:

link_directories(${IS_SDK_DIR}/build)

Doing so , the cltool utility can be built successfully, otherwise the following linking error appears:

100%] Linking CXX executable cltool
/usr/bin/ld: cannot find -lInertialSenseSDK
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/cltool.dir/build.make:99: cltool] Error 1
make[1]: *** [CMakeFiles/Makefile2:76: CMakeFiles/cltool.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

@andreucm Can you confirm if this is still an issue with the latest 2.2.0 release in your build environment? We are also working on a new 2.3.0 release (develop branch) which has significant refactor around CMake and our build scripts, etc.

If this is no longer an issue, please let me know so we can close this issue.
