"add_subdirectory(/path/to/microgl)" is not usable

Please, remove examples from root CMakeLists.txt, because it's broke build process:

@Azq2 We actually use it as part of the CI and build testing in the cloud. There might be an issue with this example, i will test it

I use microgl in embedded projects with cross compiling. In my problem find_package() finds SDL2 headers from the host package libsdl2-dev which is for amd64. But I build my project for arm-linux-gnueabi with a "libc only" environment.

Maybe this is more my problem and I should simply turn off pkg-config in cmake. But, I think if(DEFINED SDL2_FOUND) is not enough for skipping tests.

Maybe one of these variants is cleaner for the library users:

1. Tests are disabled by default, but can be enabled with option.
2. Tests are enabled by default, but can be disabled with option.

Hi @Azq2 I get it. Do you have a proposition ? Maybe adding a flag through cmake to add examples ? I am open to that

2. Tests are enabled by default, but can be disabled with option.

I prefer with this one, to make sure the micro-gl is usable and reliable.
