[question] What heppened with the CMakeLists.txt file in the repository root?

[yurivict]

We have the FreeBSD port graphics/glad with version 0.1.36 that builds a cmake-based project.
Now 2.x.x doesn't have a cmake file any more.
Was the project re-written in Python?

[Dav1dde]

The CMake files just moved into the cmake directory. Usage changed also a bit, e.g. see one of the examples

[yurivict]

cmake/CMakeLists.txt doesn't build anything though.
It doesn't have the add_library(glad ...) instruction.
No other CMakeLists.txt has such instruction.

[Dav1dde]

Correct, glad was never supposed to be built either, it should be integrated directly in tools which use it.
