Okay concept and execution for Emscripten build process in the last commit:

if(EMSCRIPTEN)
    set(FMT_WASM_SOURCES
        ${FMT_SOURCES}
        ${FMT_HEADERS}
    )
    add_executable(fmt_wasm
        ${FMT_WASM_SOURCES}
    )
    target_include_directories(fmt_wasm PRIVATE
        ${CMAKE_CURRENT_SOURCE_DIR}/include
    )
    set_target_properties(fmt_wasm PROPERTIES COMPILE_FLAGS "-Os -s SIDE_MODULE=1 ")
    set_target_properties(fmt_wasm PROPERTIES LINK_FLAGS    "-Os -s WASM=1 -s SIDE_MODULE=1 -s STANDALONE_WASM --no-entry")
    set(CMAKE_EXECUTABLE_SUFFIX ".wasm")

endif()

This should work we will need to test linking.

elif [ "$TYPE" == "emscripten" ]; then
        mkdir -p build_$TYPE
      cd build_$TYPE
      $EMSDK/upstream/emscripten/emcmake cmake .. \
       ${DEFS} \
       -DCMAKE_TOOLCHAIN_FILE=$EMSDK/upstream/emscripten/cmake/Modules/Platform/Emscripten.cmake \

      cd ..
