Hello! I found, that CMake in media-libs/sdl2-ttf is checking for opengl only for sample programs (glfont and showfont), which are, even if selected, only built, but not installed on merge. objdump -x /usr/lib64/libSDL2_ttf-2.0.so.0.2000.2 also shows no signs of opengl dep. I'm suggesting to drop both virtual/opengl dep from ebuild, and building of sample programs, if they're not installed, but setting SDL2TTF_SAMPLES to OFF. These changes allowed to build and use SDL2TTF of my system. If this won't work, then, please, at least change dep from virtual/opengl (which is pretty outdated, as it depends on X11), to use glnvd (as CMake is also preferring).
