Ncnn: TX2 compilation failed

I followed the
https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-nvidia-jetson
instructions, but with errors listed below:

CMake Error at CMakeLists.txt:45 (find_package):
By not providing "FindVulkan.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "Vulkan", but
CMake did not find one.

Could not find a package configuration file provided by "Vulkan" with any
of the following names:

VulkanConfig.cmake
vulkan-config.cmake

Add the installation prefix of "Vulkan" to CMAKE_PREFIX_PATH or set
"Vulkan_DIR" to a directory containing one of the above files. If "Vulkan"
provides a separate development package or SDK, be sure it has been
installed.

Cannot figure out why. Thx.

tensorrt is better in TX2, highly recommended.

or u can see https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-nvidia-jetson for more vulkan in nVIDIA TX serials

[veepersgit]

@kalcohol Thank u for ur recommendation! I will track the tensorrt line, but the ncnn line is still a problem. Can u figure it out?

@veepersgit more detials in https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-nvidia-jetson

[veepersgit]

@kalcohol Sorry，I think u might not understand my question here. I followed the instructions of https://github.com/Tencent/ncnn/wiki/how-to-build#build-for-nvidia-jetson with each step checked, but got errors mentioned above.

[veepersgit]

Here's the command line:
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchains/jetson.toolchain.cmake -DNCNN_VULKAN=ON -DCMAKE_BUILD_TYPE=Release ..

@veepersgit you need to upgrade cmake

[veepersgit]

It worked, thx.

Hello，what is ncnn‘s advantage over tensorRT ？Will it be more faster？

[sunjunlishi]

@veepersgit it worked。到底哪个方法起作用。which method ok ？
