can't build cpp branch

[Jpower2023]

Hello,

I'm currently trying to build cam_overlay_cpp on Crankshaft-NG. Unfortunately, I'm getting the following error message in CMakeLists.txt:
No project() command is present. The top-level CMakeLists.txt file must
contain a literal, direct call to the project() command. Add a line of
code such as
project(ProjectName)

near the top of the file, but after cmake_minimum_required().

CMake is pretending there is a "project(Project)" command on the first
line.
This warning is for project developers. Use -Wno-dev to suppress it.

CMake Error at /usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
Could NOT find OpenGL (missing: OPENGL_opengl_LIBRARY)
Call Stack (most recent call first):
/usr/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:393 (_FPHSA_FAILURE_MESSAGE)
/usr/share/cmake-3.16/Modules/FindOpenGL.cmake:397 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
src/Gl/CMakeLists.txt:4 (find_package)

-- Configuring incomplete, errors occurred!
See also "/opt/crankshaft/cam_overlay-cpp/CMakeFiles/CMakeOutput.log".

Does anyone have any ideas regarding this?
I've already tried modifying RaspberryPi.cmake l (ike this post #25 (comment)), but without success.
