Compiling OpenCV project using CMake results in build errors while regular compilation works fine

I downloaded CMake and OpenCV using homebrew, I am trying to run a simple openCV program that opens my camera and starts to stream a video. I can compile my program regularly using the command line with: clang++ -std=c++11 mvu_lib_cpp.cpp -o execute 'pkg-config --cflags --libs opencv4' However when I try to build and compile my project using CMake I am running into trouble and errors.

Script:

#!/bin/bash

SDK=/Users/Iftach/Library/Android/sdk
CMAKE=$SDK/cmake/3.18.1/bin/cmake
NDK=$SDK/ndk/23.0.7272597

export CXX=$CXX

$CMAKE -DCMAKE_CXX_FLAGS=$STD -DCMAKE_TOOLCHAIN_FILE=$TOOLCHAIN_FILE -DANDROID_ABI=$ABI -DANDROID_NATIVE_API_LEVEL=$MIN_SDK -DANDROID_STL=$STL $CMAKE_ARGS

CMakeLists.txt:

    VERSION ${PROJECT_VERSION}
    SOVERSION 1
    OUTPUT_NAME "mvu_cpp"
    XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY "MacOS_ID"
)

For some reason I am getting a linkage problem, the script runs smoothly but when running make I am getting an error in the middle of the build

script output:

./create_mvu_makefile.sh: line 12: -o: command not found
