The libclc package contains library requirements of the OpenCL C programming language (provides header files but no libraries itself).
Install libclc by running the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
-G Ninja .. &&
ninja
Now, as the root user:
ninja install
