How to build musl binaries in ubuntu-22.04?

[Masber]

Dear rdkafka community,

I am trying to build a linux musl binary of my project which uses rdkafka but I am unable to do so, this is the error I am getting:

warning: [email protected]+2.3.0: Compiler family detection failed due to error: ToolNotFound: failed to find tool "x86_64-linux-musl-g++": No such file or directory (os error 2)
error: failed to run custom build command for rdkafka-sys v4.8.0+2.3.0

Caused by:
process didn't exit successfully: /home/runner/work/manta/manta/target/dist/build/rdkafka-sys-ec32d5424a0c0a2e/build-script-build (exit status: 101)

Compatibility with CMake < 3.10 will be removed from a future version of

Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax

Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.
