<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have a project which uses the CMake 3.10.1 and CUDA nvcc compiler and I am using the new project(projectName LANGUAGES CUDA) instead of find_package(CUDA) to do so. I want CMake to use a different (explicitly defined) path for nvcc compiler
than the installed version. Before calling project(projectName LANGUAGES CUDA), I declare CUDA_TOOLKIT_ROOT_DIR via an include of a file which defines our third party library variables, but it always finds the installed version. I know that CUDA_TOOLKIT_ROOT_DIR
was meant for the find_package(CUDA) script, but the documentation doesn't seem to specify how to use the new project method of including nvcc.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a way to specify a different nvcc location using the new format?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Excerpt from CMakeLists.txt: <o:p></o:p></p>
<p class="MsoNormal">…<o:p></o:p></p>
<p class="MsoNormal">include(${CMAKE_CURRENT_SOURCE_DIR}/../../../build/thirdparty_versions.cmake) #defines CUDA_TOOLKIT_ROOT_DIR to specified CUDA root with bin/nvcc below it.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Below is a portion of my output: <o:p></o:p></p>
<p class="MsoNormal">…<o:p></o:p></p>
<p class="MsoNormal">---------------CUDA_TOOLKIT_ROOT_DIR:C:/thirdparty/CUDA/v8.0

<p class="MsoNormal">You can see that the CUDA compiler found was the intalled version, not C:/thirdparty/CUDA/v8.0<o:p></o:p></p>
