Error Building

[PixelDud]

Running: cmake -DLIBOBS_INCLUDE_DIR="../../obs-studio/libobs" -DCMAKE_INSTALL_PREFIX=/usr ..

I get:

-- The CXX compiler identification is unknown
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.


-- Configuring incomplete, errors occurred!

I'm running Elementary OS 5.1.7, any clue how to fix this?

To solve your problem, you need to do apt install libobs-dev

I did that and it didn't work.

Thanks for the answer though.

apt install build-essential libobs-dev solved the problem for me on ubuntu 20.04
