Use of emconfigure for wxWidgets

Hi, I am using the following documentation.

https://emscripten.org/docs/compiling/Building-Projects.html

`emcc -v
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 2.0.17
clang version 13.0.0 (/b/s/w/ir/cache/git/chromium.googlesource.com-external-github.com-llvm-llvm--project 3b677b81cec7b3c5132aee8fccc30252d87deb69)
Target: wasm32-unknown-emscripten
Thread model: posix
InstalledDir: /home/faisal/Desktop/emsdk/upstream/bin
`

I am looking to use the ./emconfigure file for the wxWidgets library in Ubuntu.
It could not find the gtk library. Simple execution of ./configure for g++ works just fine.
