I'm using Visual Studio and the stb_image.h library.
If I call stbi_load in my program I get the following errors:
Error 3 error LNK2019: unresolved external symbol _stbi_load referenced in function "public: bool __thiscall CubemapTexture::Load(void)" (?Load@CubemapTexture@@QAE_NXZ) ...\CubemapTexture.obj
Error 40 error LNK2001: unresolved external symbol _stbi_load ...\Texture.obj
