I don't know how can I fix this but the error is this : renderer-378788.o : error LNK2019: unresolved external symbol "public: __cdecl TGAImage::TGAImage(int,int,int)" (??0TGAImage@@qeaa@HHH@Z) referenced in function main

What is the build setup? Have you used the cmake description of the project?

I'd recommend using it instead of compiling individual c++ files by hand.
