For the building of Hypr with the Ubuntu instructions (i run mint 20.2 which is basically ubuntu), the installation dependencies also require build-essential, otherwise a CMAKE_CXX_COMPILER error will occur. I recommend updating the dependency list to also include build-essential.
CMake Error at CMakeLists.txt:2 (project):
No CMAKE_CXX_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.
