Cmake Ninja backend support

[SeungheonOh]

$(Configuration)... to ${Configuration} for proper ninja backend support.

Currently ninja backend fails to build with following error message:
"ninja: error: build.ninja:1094: bad $-escape (literal $ must be written as $$)"

It seem that it is still failing. Any idea?

Any idea?

I think the error itself is

  '..\\makefont' is not recognized as an internal or external command,
  operable program or batch file.
C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppCommon.targets(170,5): error MSB6006: "cmd.exe" exited with code 9009. [C:\projects\freetype-gl\build\demos\generate-embedded-font.vcxproj]

which unfortunately I have no clue of, but "..\makefont" looks like it's a some sort of path error.

makefont is built by the library and I imagine it is lacking a .exe for windows.
