Building a "shared object" (DLL) in Windows includes 2 steps: - specify __declspec(dllexport) when building the library itself. MSVC will disallow itself from optimizing these symbols out and reference them in the PE's Exports-Table. Further, a static link library will be generated. This library contains the symbols which are exported via the declsepc above. The __declspec(dllexport) becomes part of the symbol-signature (like parameter types in C++ are 'mangled' into the symbol name, the export specifier is mingled with the name) - specify __declspec(dllimport) when using the library. This again mingles the declspec into the name and declares the function / variable with external linkage. cmake automatically adds -Dgit2_EXPORTS to the compiler arguments when compiling the libgit2 project. The 'git2' is the name specified via PROJECT() in CMakeLists.txt.
