How to build on linux?

[VineetTambe]

I am trying to build and run the project in a linux environment.
These are the steps I have followed (you can use the same to reproduce):

1. Since i am using g++ to build - I have removed __declspec(dllexport) from /include/TopotagDetection.hpp
2. Then I ran cmake -S . -B build in the CMakeList.txt folder
3. Then cmake --build build

The error I get is somewhat strange I do not understand how to debug it:

/usr/bin/ld: CMakeFiles/TopoTag.dir/test/main.cpp.o: in function `main':
main.cpp:(.text+0x4e): undefined reference to `LoadConfigParams(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
/usr/bin/ld: main.cpp:(.text+0xbb): undefined reference to `DetectTopotag(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::vector<TopotagPose, std::allocator<TopotagPose> >&)'
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/TopoTag.dir/build.make:85: TopoTag] Error 1
make[1]: *** [CMakeFiles/Makefile2:76: CMakeFiles/TopoTag.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

As per the error the function signature of LoadConfigParams and DetectTopotag are not matching. But I verified that they are the same.
I have also tried type casting the string input to LoadConfigParams and DetectTopotag in test/main.cpp using (std::string) but I still get the same error.

Any help would be much appreciated :)
