Issues with Boost Library for x86_32 Architecture on Ubuntu 22.04 – How to Manage Conflicts with x86

I'm working on a C++ project that uses the Boost program_options library on Ubuntu 22.04 system with an Intel Core i7 processor. I've successfully compiled and run the project for x86_64 architecture using the following command:
g++ program.cpp -m64 -static -lboost_program_options -o compiled/program.out

So when I try to compile for x86_32 architecture using -m32, I encounter the following error:
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../libboost_program_options.a when searching for -lboost_program_options
/usr/bin/ld: skipping incompatible /usr/lib/libboost_program_options.a when searching for -lboost_program_options
/usr/bin/ld: cannot find -lboost_program_options
collect2: error: ld returned 1 exit status

I've attempted to install the 32-bit Boost library using 
sudo apt-get install libboost_program_options-dev:i386

but it conflicts with the 64-bit version.

How can I effectively manage Boost library installations for both x86 and x86_64 architectures on the same system? Are there any alternative approaches or workarounds to avoid conflicts and ensure compatibility?
Solution
Was receiving a linker error indicating that it cannot find the 32-bit Boost library, and I noticed that some of my project's dependencies might also require specific 32-bit libraries , but I was able to manage these with pkg-config . Thanks
