SDL2 include dir not found

[nikita-yfh]

I tried build SDL_FontCache with CMake, but it not build:

nikita ~/c++/hagen/src/SDL_FontCache $ cmake .
-- The C compiler identification is GNU 10.2.0
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Check for working C compiler: /usr/bin/cc - skipped
-- Detecting C compile features
-- Detecting C compile features - done
CMake Error at CMakeLists.txt:12 (message):
  SDL2 include dir not found


-- Configuring incomplete, errors occurred!
See also "/home/nikita/c++/hagen/src/SDL_FontCache/CMakeFiles/CMakeOutput.log".

The SDL2 libraries installed. How to build it?

Seems like an issue with your Cmake file rather than with SDL_FontCache. Do you specify where to find your SDL2 dependencies? You'd need a line like:
include_directories(${SDL2_INCLUDE_DIRS} ${SDL2_IMAGE_INCLUDE_DIRS} ${SDL2_TTF_INCLUDE_DIRS} ${SDL2_MIXER_INCLUDE_DIRS})
You can also look here for additional files that you may need to add in order for CMake to find the dependencies: https://github.com/aminosbh/sdl2-cmake-modules
