问题 How do I correctly link to CUBLAS in CMake 3.11 ? In particular, I'm trying to create a CMakeLists file for this code. CMakeLists file so far: cmake_minimum_required(VERSION 3.8 FATAL_ERROR) project(cmake_and_cuda LANGUAGES CXX CUDA) add_executable(mmul_2 mmul_2.cu) This gives multiple "undefined reference errors" to cublas and curand. 回答1: Found the solution which is to add this line in the end of the CMakeLists file: target_link_libraries(mmul_2 -lcublas -lcurand) 来源： https://stackoverflow

问题 find_package(GTK) How can I make it output something so that I can know whether it finds something or not? Platform: windows XP 回答1: You can use the message command as in: FIND_PACKAGE(GTK) IF (${GTK_FOUND}) MESSAGE(STATUS "Found GTK.") ELSE (${GTK_FOUND}) MESSAGE(STATUS "Could not locate GTK.") ENDIF (${GTK_FOUND}) Or, if you want it to abort if GTK isn't found: FIND_PACKAGE(GTK) IF (${GTK_FOUND}) MESSAGE(STATUS "Found GTK.") ELSE (${GTK_FOUND}) MESSAGE(FATAL_ERROR "Could not locate GTK.")
