I have a project that requires some dependencies compiled with GCC 9.2.0. The project also depends on CUDA, as I have some kernels. I am using CMake in Linux. For the project itself, I am also compiling with GCC 9.2.0
If I only specify project(MyProject CXX CUDA) and compile it with no kernels, everything works fine, and the linking line is the following:
[100%] Linking CXX executable PerformanceTest
cd /home/jjcasmar/projects/Tests/Eigen/build/Release/PerformanceTest && /usr/bin/cmake -E cmake_link_script CMakeFiles/PerformanceTest.dir/link.txt --verbose=1
/usr/bin/c++ -O3 -DNDEBUG CMakeFiles/PerformanceTest.dir/TestPerformance.cpp.o -o PerformanceTest /usr/local/lib/libbenchmark.a -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lm /usr/lib/libdl.so -lpthread /usr/lib/librt.so
If I add a .cu file to the project, then CMake changes the linking line and the project fail to link

The difference is that when I add a .cu file which is compiled with nvcc, the linking line contains -L/usr/lib/gcc/x86_64-pc-linux-gnu/8.3.0.
Is there any way to fix this?
