Thanks! It seems that the headers can be easily shipped without much effort inside the inst/include/CL/, working at least for both Debian and Windows for now. (Updates available on https://github.com/Quirinms/GeneralizedUmatrixGPU/tree/main)
However, there comes another problem afterwards with a dynamic library/shared object (Win/Debian). After finding the headers, following message appeared: D:\rtools45\x86_64-w64-mingw32.static.posix\bin/ld.exe: cannot find -lOpenCL: No such file or directory similar in Debian: Error: package or namespace load failed for ‘GeneralizedUmatrixGPU’ in library.dynam(lib, package, package.lib): shared object ‘GeneralizedUmatrixGPU.so’ not found For Windows there is more output using -lOpenCL --verbose: g++ -std=gnu++17 -shared -s -static-libgcc -o GeneralizedUmatrixGPU.dll tmp.def RcppExports.o trainSESOM.o -Ld:/RCompile/CRANpkg/extralibs/OpenCL/lib/x64/ -lOpenCL --verbose -Ld:/rtools45/x86_64-w64-mingw32.static.posix/lib/x64 -Ld:/rtools45/x86_64-w64-mingw32.static.posix/lib -LD:/RCompile/recent/R/bin/x64 -lR Using built-in specs.
