Static Libraries Dependencies

`A <- B <- C` (B uses A), when you build A, B, and C as static libraries, and another target uses A, B, C. In the `target_link_libraries()`, the order should be `target_link_libraries(C, B, A)`.

Compile Static Libs

We want to provide our C++ application as a shared library and support the old version of GCC like 4.x.x.

  1. Thus, we need to build all static libraries with -fPIC.
  2. We should add -D_GLIBCXX_USE_CXX11_ABI=0.
