I have pytorch installed and working no problem, making use of the GPU. While trying to install Libtorch, I kept getting errors like:
CUDA_TOOLKIT_ROOT_DIR not found or specified
I can't find where this path is. I will edit the post with the output of commands.

I've tried following all the help to change my compiler to use GCC instead of Clang (on macOS) as I would like to try to use __gnu_pbds::priority_queue instead of the STL version, and it still appears that CMake uses Clang. I've made a toolchain that looks like this:
and set it to be used in the CMake profile.
However, it appears CMake skips actually using the compiler - here is the CMake output:

Any idea how can I fix this issue ?
Never, ever do an in-source build. cmake . is always wrong. It even says so in the MySQL documentation: https://dev.mysql.com/doc/connector-cpp/8.0/en/connector-cpp-installation-source-cpp.html
This worked for me:
$ git clone --depth 1 --branch 8.0 https://github.com/mysql/mysql-connector-cpp.git
$ cmake -G "Unix Makefiles" -S mysql-connector-cpp -B mysql-connector-cpp-build -DCMAKE_BUILD_TYPE=Release
$ cmake --build mysql-connector-cpp-build
It also looks like you're missing the SSL dependency. If you're running a Debian derivative (Ubuntu, Mint), you can install this with:
$ sudo apt install libssl-dev
When using the mingw-32 cmake the code from https://github.com/KhronosGroup/Vulkan-Loader fails to compile this is the cmake command I am using:x86_64-w64-mingw32-cmake -DVULKAN_HEADERS_INSTALL_DIR=/usr/x86_64-w64-mingw32/ -DVulkanRegistry_DIR=/usr/x86_64-w64-mingw32/share/vulkan/registry/ -DUSE_MASM=OFF ..

Thank you.
P.S. Distrobution is manjaro.
The problem was that I had a MASM assembler. Which caused it to attempt an assembly thing that it failed to do.
I am trying to install LightGBM-gpu on Centos. It seems boost 1.56 can be find, but this error occurred.I google it all day but can not solve it.

This question was cross-posted to the LightGBM issues page as microsoft/LightGBM#3613. The issue was solved there.
Updating CMake to at least version 3.14 fixes this issue.
Please help fix the error on Installing Connector/C++ from Source, while "make clean". There are two parts to the question:
