Embed resources directly into the binary to reduce dependencies to files in the filesystem at runtime.

CMake:

include(create_resource.cmake)

file(GLOB resources ${CMAKE_CURRENT_SOURCE_DIR}/example.cc)
create_resource(${CMAKE_CURRENT_SOURCE_DIR} "${resources}" mysrc)

add_executable(res-example EXCLUDE_FROM_ALL example.cc)
target_link_libraries(res-example mysrc mysrc-res)

C++ Code

auto r = mysrc::get_resource("example.cc");
printf("%zu %p\n", r.size_, r.ptr_);
printf("%.*s\n", static_cast<int>(r.size_), static_cast<char const*>(r.ptr_));
